FAQ

RGB and 300 ppi (dpi) saved as jpegs. I usually compress to 9 or 10, but I know I could go a lot lower. There are a lot of old posts, some made by me, but maybe hard to find.

p.s any black and white stuff - change color to grayscale

Hmmm...why isn't there any text in any of the older posts about dpi and color settings for photoshop? This information would be very helpful for me. This problem occurred using both Safari and Firefox. Thanks.
