í’m looking for website that offer a free online banner maker…can anyone suggest?
All of them will be limited editions. You have to use a professional software like fireworks, flash, photoshop vs.
I recommend you my favorite flash banner maker site : http://www.banner4five.com
Hope I could help! Good luck with your projects! 
try www.bannersketch.com, I like it.
Or Paint Shop Pro by Corel. It’s priced pretty good and will do what people need.
