"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

If we increase the resolution, the quality of the image would be poor.
However, I can convert to jpeg if you want (but it will also lose some quality).

Gplana, this is what I am trying to accomplish. Increase the resolution of this pic maintaining the quality. I know there are some software that can increase de quality of the picture. I need to post this pic in a website but it's too small ....( the pic is too small)

Hi Italiabella,

I'm guessing that you want to improve the quality of that image, but increasing the resolution isn't going to do it — nor will converting it to JPG. Here's the info about the image:

image info
As you can see, it is 234x175 pixels; it is compressed (with LZW compression), which makes it lose quality; and the color depth is just 256 (i.e., 8-bit color — for good quality, you want at least 24-bit color). Here's the image with the pixels doubled both horizontally and vertically (so it is 468x350), and converted to JPG:

But as you can see, the quality isn't really better. We may be able to make some minor improvements to it using image enhancement techniques, but for a really good quality image, you need to go back to the source and get a much higher quality image from the get-go. Regards, Joe

Our messages just crossed. If you need more pixels in order to post at the website, I can make it whatever size you want (and I can make it a JPG). Just let me know the horizontal (or vertical) pixels that you want and I'll post the JPG for you. I assume you want to retain the aspect ratio (i.e., keep it proportional), so all I need is either the horizontal or vertical pixels (the other dimension will be sized automatically to retain proper aspect ratio). Regards, Joe

yes Joe, I am trying to increase the quality of the image so that I can enlarge it without loosing the quality of the picture
ItaliabellaAuthor Commented:
horizontal Joe will be great !
Joe Winograd, Fellow&MVEDeveloperCommented:
Here's a better quality version of that image:

Note that it is a JPG with 400x300 pixels and 24-bit color:

image info better quality
Let me know what horizontal or vertical pixel size you need and I'll post it. Regards, Joe

@Joe: LZW is used on TIFFs also, and it's a lossless compression:
Joe Winograd, Fellow&MVEDeveloperCommented:
> horizontal Joe will be great !

How many horizontal pixels do you want? The better quality image that I posted above is 400 horizontal pixels. How many do you need in order to be able to post at the website?
ItaliabellaAuthor Commented:
Joe I really don't know ... I need to post it on a website therefore I assume the highest the pixilation is the better quality I get when I upload or enlarge the pic..
Joe Winograd, Fellow&MVEDeveloperCommented:
Good point, Dan! LZW is, indeed, a lossless compression. I had lossy JPG on the brain. :)  Serious brain cramp! Thanks for the correction. Regards, Joe

Joe Dan you are above my head :) I am lost...:)

> I really don't know

You need to find out.

For example, I recently tried to upload an image and received this error message:

image too small
So I had to make the image 888x482 pixels for that particular site. I can make it whatever size you want, but keep in mind my earlier comment — increasing the pixels will not increase the quality.

Don't worry about it. Not anything you need to be concerned about for the task at hand. Regards, Joe

You're sure you have the right to use it? If you bought it from there then you already have a high res version of it.

Yup, thanks.
I have the extension, so I don't visit the site. And Tiny Eye sure makes more sense than Tin Eye :)
there are softwares around that claim to do it; but i never used them :

Hi nobus,
I haven't used those, but I have used GraphicsMagick to enhance images with some success. I wrote a program called EnhanceImage that runs GM with various parameters (such as contrast, gamma, and quality). It is for a client who uploads images of his products for sale at his website and he is very happy with the enhanced images. It's important to note that he isn't trying to deceive prospective customers with the enhanced images. His strong feeling is that the real products look much better than the photos straight from his camera, whereas the images from the EnhanceImage program look much more like the actual item. Regards, Joe
>>  real products look much better than the photos straight from his camera,   <<  then he needs anopther camera, or change the way he takes pictures (other lighting, position, background etc..)
Joe Winograd, Fellow&MVEDeveloperCommented:
The camera is fine — a very high-quality one with an extremely well-known brand name. The issue is lighting. It's very difficult to get adequate lighting based on the nature of the products and where they are stored.
