Pagespeed has indicated I need to change my images from png and jpeg to a next-gen format.  I found a place online that converted my png to jpeg 2000.  Now I need to know how to load both files rather than just the one for my images to be optimized.

I am using Wordpress and I don't see a means to include both files when I want to insert the image in a page.


Please tell me how to do this or tell me another means to get my images in next-gen formats.

Hi Experts,

I recently consolidated a number of contacts that were duplicated in my contacts list on my Android S9+ mobile phone.

Now I've noticed that a lot of the consolidated contacts have the wrong avatar of the persons face, in many cases, the avatar on the contact is of a totally different person than who the contact in my phone really is.

Can anyone explain the best way to fix this so that the pictures on the contacts are correct? Please include step by step instructions if possible as I'm relatively new to Android phones, being an Iphone user for many years.

Many thanks for any help.

Regards, Andrew
Using Microsoft Access (2003)
I have a form with a text box called PicFileName and an Image Control called PersonImage
The intent is that the following code will cause .jpg (picture) to appear in PersonImage, without the .jpg being embedded in the table behind this form (in order to save space)
The following code accomplishes this perfectly:

Dim strPicName As String
Dim strPicPath As String
Dim strSource As String

strPicPath = C:\Pix                 C:\Pix is the folder containing the jpg
strPicName = ABCD.jpg       ABCD.jpg is the filename of the picture

strSource = "" & strPicPath & strPicName & ""              in this case it will be C:\Pix\ABCD.jpg

If Not IsNull(Me.PicFileName) And Me.PicFileName <> "" Then
    Me.PersonImage.Picture = strSource
End If

As I said this works perfectly in all computers on my LAN, EXCEPT for ONE which returns an error 2114 saying that this code is not supported OR the jpg is too large!  I have reduced the size of the .jpg to a few K, to no avail.

ALL COMPUTERS ON THE LAN USE THE SAME OS (Win 10 Pro), AND THE SAME VERSION OF ACCESS, AND GET THEIR JPG FROM THE SAME FOLDER,  and the above process runs perfectly for the last six years!!

QUESTION: What needs to be adjusted in the one computer where this is not working?
I have files with a DWG extension.  They were made a bunch of years ago and are supposedly blueprints. they are about 100KB files.  They've been sitting on a thumb drive for years.

I've tried opening them with irfanview and LibreCAD.  Both say they can't open them.

I used https://www.zamzar.com/convert/dwg-to-pdf/ for one of them and it made a PDF with some rectangular shapes / lines, but likely not all that shoudl be there and not aligned correctly (1 rectangle is off to the side).  Is it because they are old and newer programs cant render them correctly? Or they corrupt?

Any recommendations on a universal viewer or something that might be able to open the files?  We're looking to make PDFs or something so we can print them on a large paper printer at staples.
Hi All

Do we have any way to find out about the image quality using  tensorflow.
Actually I need high quality image to be accepted and need to reject the rest one.

Please share any advice on same.

Microsoft Photos keeps popping up when I connect my iPhone to the PC.
How can I stop it from doing it?

(Object reference not set to an instance of an object)

The following code (sometimes) give the above error only if the file is a (multi page tiff file with a large number of pages)  e.g.  400 pages or 500 pages. Not on a specific page.
and when I check     PictureBox1.Image     I find it = null!
If I reRun my software it works fine on the same page that it stopped on.
I feel it is something related to memory   (e.g.   executing the next line before full load .....)
Any help is appreciated.

PictureBox1.Image = Image.FromFile("C:\ImgFolder\ImageName.tif")
Dim NoOfPages As Long = PictureBox1.Image.GetFrameCount(Imaging.FrameDimension.Page)

For J = ImagePageFrom - 1 To ImagePageTO - 1
       PictureBox1.Image.SelectActiveFrame(Imaging.FrameDimension.Page, J)    'the error is on this line
       PictureBox1.Image.Save("C:\ImgFolder\ImageName.Gif", Imaging.ImageFormat.Gif)
PictureBox1.Image = Nothing
I am getting error when installing a program in windows 10. I have attached a screen shot.

How can i obtain the dimensions of a jpg image before displaying it on the page?

For example:


I want to use the dimension info to display the image with a certain surface area, so I would need to know the aspect ratio first.

For example, what is the code to display the image with an area of say 160k pixels ?

Microsoft Office Picture Manager
Microsoft Office Picture Manager was included in Office 2003, 2007, and 2010, but not in 2013 or 2016. Now that Office 2019 is here, the bad news is that it is still missing, but the good news is that the same no-cost method that works to install it with Office 2013 and 2016 also works with 2019.
Are there any builti-in tools in Windows 10  to capture JPG images from an MP4 video file? If not, what is the best free app to do this? Thanks!
I am trying to copy over a photo library approx 14GB from a mac hard drive connected via external usb connection to my desktop on my macbook.
The hard drive keeps freezing up whenever I try to copy it via finder. I also tried to do first aid on the drive via Disk Utility. My guess is that the hard drive is very close to failure but I can browse the files and folders. How can I get these photos recovered?
I had selected 2 pictures from pictures folder to be used as background. I do not wish to keep them as background. In another word I wanted to delete them from the location in which they are stored at. The problem is they do not show up in the default location for the background. See screen captures. How do I go about deleting them? The 2 pictures are 1.The Water Falls and 2.The Red Rose.

Thank you.

I need the way to select one area and insert color inside, while the background details are still shown, to the picture, in GIMP.

Or is it not achievable to this, in MS paint?
Within MS painter, how to fill part of area (highlighted below), with specific yellow colour?

How to put a date-time stamp on a PDF file with free software - Foxit Reader
I previously published an Experts Exchange video Micro Tutorial that describes how to scan documents to a PDF file using an excellent, free product called Foxit Reader:

How to scan to a PDF file with free software

N.B.: As with any "free" software, there may be restrictions, which are always specified in the software's licensing agreement, typically known as the End-User License Agreement (EULA). I encourage you to read the entire EULA of this product to be certain that you are in license compliance.

This new video Micro Tutorial shows where to download the free Foxit Reader and explains how to use it to place a date-time stamp on a PDF file.

1. Download and Install the Free Version of Foxit Reader

Visit the website for Foxit Reader at Foxit Software:


Select the language and O.S. from the drop-downs, then click the big, red Download button:

After downloading, run the installer.


2. Run Foxit Reader

The installer creates a Foxit Reader program group with a shortcut to the Foxit Reader program.

Click the shortcut to run Foxit Reader.


3. Put a pre-defined date-time stamp on the PDF

After opening a PDF file, click the Comment menu.

Click the drop-down on the Stamp button.

Click one of the five pre-defined Dynamic Stamps, all of which have a date-time stamp.

Position the mouse wherever you want the stamp and click to place it.


4. Create a custom date-time stamp

Click the drop-down on the Create button.

Click Create Custom Dynamic Stamp.

Select a Stamp Template and fill in the options in the dialog box.

Click Add.

Click OK.

Hi, guys,

I am using pdfimages.exe command line program (http://www.foolabs.com/xpdf/download.html), to convert pdffiles to images... I want the generated images in jpg format. The software has an option "-j" to do that. My question is how to send to a cmd line program the parameters thru the shellapi... I mean, I have to send to the cmd line the next string: "pdfimages -j source.pdf new". Any ideas?

Prepare for the PMI Agile Certified Practitioner (PMI-ACP)® exam, which formally recognizes your knowledge of agile principles and your skill with agile techniques.

I want to simulate panoramic image functionality, physically accurate with the Unreal Engine 4 (UE4).
Similar to the functionality in smartphones today, but in two axis (the camera is also turned vertically).

Known is the horizontal / vertical FOV of the camera lens (eg. 18 degree horiz., and 24 degree vert.), and that of the panorama (eg. 150° horiz., and 80° vert.).

The problem is, no matter how wide the FOV is set in an unreal engine camera (e.g. 150° horiz., and 80° vert.), the engine seems to straighten the curves that are immanent in wide angle / panoramic images.

How can I get the real, not corrected image, with the typical (spheric) distortion?

Here a simplified example (attachment:
The black lines show two walls from the top view. The camera is mounted a bit above the wall's height.
Although the FOV of the camera is very large, it shows the two lines parallel:

The blue lines are representing the desired and resulting look of the walls, if the scenery isStraightened view vs. Panorama view scanned as a panorama.

Is there a way to increase the size of the thumbnail photos in Windows 10 Explorer?  The "Extra Large" View doesn't cut it for my aging eyes.  I would be happy to buy a third-party program, if necessary.


Why does Power Point (Mac 2018 version) darken images?

When I run the presentation, all my images get darkened. And some become unusable.

Is this a setting i can turn off? I want the images to show exactly as they are in Power Point.

So i have a SharePoint Word Doc that has a jpg. When i look at it in Word Online (Office 365) the image is shifted to the right. I see the margin on the left but no margin on the right. When i view it in the Word App it looks correct (e.g. it's centered and takes up the full page).
Following is a question from Image Signal Processing Book:

Determine the actual physical measurement in millimeters of an image with 1400 rectangular pixels and a resolution of 72 dpi.

Is pixel a dot ?
