Gif is not a great filetype, especially if you want a crisp image. What are your pixel dimensions?
For web, it makes no difference what the dpi is, only the final pixel dimensions so once you have that as you want, use 'Save for Web and Devices' and you can lower the quality - 100% being max and 0% being lowest. I wouldn't save anything below 55%. For a 600kb image, your dimensions must be rather big.
yes 600kb is for a large image. My website is for stained glass. Some of my pages only have a 2 or 3 images. but most have more medium and small images. What my save for web and devices tool (CS5) does is convert the image to a gif. Is there another option to keep it as a jpg? Also how do I change that percentage to a higher resolution? That is what I want to do, but how?
OK I figured out that I have options when I go to the save for web and devices box and can keep it as a jpg and adjust the percentage as Rik says. So I will mark his as correct. But I still would like to be able to get something between the original file size and the 100 percent file size but that would be experimenting with my original resolution, maybe going to 800 or 1200. Any way thanks
