I have made a banner of moving clouds about 100 px tall by 800px wide. The clouds travel from right to left. Right now I am using a gif image of a skyline and the animation loops. It size is about 60 kb. I was wondering if anyone knew how to make realistic looking clouds in vector format so I can shrink the file size of it dramatically. This is for a top banner so it reloads everytime a person goes to another webpage, thats why I want it as small as possible.
I saw the tutorial on the kirupa site but it doesnt seem realistic.
