Hello,

I am completely new to this forum so I apologize if this is posted in the wrong place. I am using Adobe Photoshop Elements 9 and have a question regarding file size/quality. So, here it goes.

 I am currently working on publication that requires all downloaded photos to be uploaded to a website that has a max file size of 20 mb. When I download an image to use for a background (some sort of a pattern that is normally somewhere around 800 x 800 size) the image is about 180 kb which is perfect. Unfortunately, the image has a poor ppi resolution and prints extremely blurry so in photoshop under image size, I increase the resolution so that the file size & resolution is bigger. This takes a lot of guessing on my part.

For example, if I increased the image resolution to 100000000 ppi, the file size would end up way over 20 mb which does me no good. So what I am wondering is, is if there is a way to optimize the the resolution of the image, given the file size limitations, without all of the guess and check?

If this looks confusing, I apologize and will gladly explain more. Any help would be greatly appreciated.
