Here is link to a free image resize app. for XP.

Multiple Image Resizer 1.0.1244.14177 (single images also)

There's a XP powertoy that makes thumbnails and gallerys.
When you are making the gallery one of the options is to make a maximum resolution ad to size down all resolution that are above that minimum. The name is HTML Slide Show Wizard. One other powertoy is the image resizer ...

The advantage of this programs is that they're made by microsoft ... and are extremely fast ...

One other non free option would be Adobe Photoshop ... Just open the JPG, Go to Menu: File -> save for web
After that you can loose alter the parameters to make your file smaller ... you can also try to see how much space the image would ocupy in .GIF format ... depending on the image it can be smaller in either of the formats ...

Download this program:
(Irfanview)

1. Open Picture
2. Hit (CTRL-R)
3. Resize based on percent
4. Save the file

you don't need to download anything, ms paint could do this if you wanted it to. open up the picture in MSPaint and then goto image > strecht and skew and put the image size you want.

sure ... and if there are 1000 files? that's why I said Xp's Powertoy ... it can handle alot of pictures at the same time ...

Hi,
I downloaded the Powertoy. I tried the Slide Show. I found it is very, very easy to present pictures on the web, and the speed is very fast. But I found the pictures' quality are not good enough. See, I have the pictures, all these pictures have the size about 700 kb. When I use Slide Show, it ask me choose picture size. If I choose 800x600, then it save these files at smaller file size. If I choose Keep current picture size, then it does not change the pictures' file size. However, no matter what I choosed, If I open the default.htm and watch the pictures on the web page, I found these pictures do not have good quality that it should have. But if I directly open the html files that contain the pictures, the files show the pictures very big, but it still not good as XP picture viewer. I am not good at HTML and VB, Java, is there any way to modify the html files, let files present pictures more nice?

I also think the JPEG files may contians two information, one is the resolution, like 1024x2048 pixals. and another is the picture size, ie length and width. If the two pictures have same resolution but different size, then the smaller size picture has better image quality. If I am right, is there a program can only change the picture size parameter?

paint is a completely suitable and free and already installed application. you don't need to know any html, VB, and java to know about images. to be frank, you need to read up about images and compression: http://www.google.com/search?q=image+compression you will find a plethora of information.

"I also think the JPEG files may contians two information, one is the resolution, like 1024x2048 pixals. and another is the picture size, ie length and width.

wrong ... It all depends on the quality of the information stored. If you have a 1024x768 with high quality (100%) and the same picture with less quality then the lesser quality picture will take less (or equal) space. It's a tradeoff ... you can't maintain the same quality on a jpeg and simply reduce the size of the file ... if you could do that ... it would be a standart and it would always happen.

What jpeg enables you is to reduce the filesize BY reducing the quality of the image. Sometimes this is acceptable. One other thing all formats allow is to reduce the image resolution ... if you reduce from 1024x768 to 640x480 the filesize will reduce and the image will retain the same quality.

If your file ocuppies 800K in jpeg format try and convert them to GIF see if they occupy less space. Have you tried this? It all depends on the 'kind' of images you are using.  And one other thing ... 2 different pictures store different information and therefore can't be compared as to their size. The only connection between them will be that they have the same resolution but one can occupy 10k and another 1Mb .. it all depends on the richness of colors, details etc.

What are you trying to do with your files? What kind of files are they? what is the resolution? do you wanna keep resolution and reduce filesize? or do you wann reduce resolution? can you try other formats (like gif?)? are they pictures, text, shapes, what?

I bought a digital camera. I want to put some pictures on the web. The pictures have 2 mega pixal resolution. These pictures look not too bad with XP Picture Viewer. But these files have about 700 kb size. I wish the web page can load these pictures fast and at meantime these pictures still look good. So I think, for example, a picture has 1600 * 1200 resolution, and displaying on computer at 16 cm * 12 cm size, if I reduce the picture resolution to 800 * 600 resolution and display it at 8 cm * 6 cm size. It should look very similar quality. Isn't it? Of cause, I understand, it will miss some details, but these two pictures won't be one clear and another very blurry. Am I right?

Just resize the images down to a reasonable dimension. 800x600 is fine. Ignore "resolution" because a web browser is going to ignore that information anyway. Dimension is ALL it cares about. Adjust your JPEG compression accordingly to get a good compromise between filesize, and quality. You will lose a little just because of the compression but that's part of the price of displaying images on the web.

Use the XP's powertoy ... that's why I use it ... ;)
It works for me... choose 800x600 and check the box "only resize pictures larger than the size selected". This will make all the files with the new resolution 800x600 and reduce the filesize.

Weed is correct about the SPAM. There is no doubt that you will soon be receiving a lot of unwanted mail.
