I sometimes use Google AdWords banner generator, but find it very basic, therefore I thought about creating something better.
Now I just finished Banimatic.com - smarter banner generator, which generates banners based on the URL supplied. Generated banners are customizable - you can switch off and remove any part of the banner, or change it the way you need it to be. They can also be animated and exports to HTML or png files. I always like products that are simple to use, but gets the job done, this was my main goal with this product too.
Any feedback is welcome.
