All I am trying to do is make a 600x450 image that has text on it. I want to use it for Craigslist. I downloaded Fireworks 8 because I have some familiarity with it, created a white canvas that is 600x450, clicked the text button, added the text, adjusted it accordingly, optimized it, and then exported it.
I go to upload it to Craigslist, and it will not accept it. Just to make sure that it wasn't a CL issue, I tried uploading another image, and it worked fine.
What am I missing here?
