currently, i have 2 flash movies on my site to rotate some banners, but as the more ad is included, the movie size increased.

so i'd like to know is there any avaliable script in php or flash that can have a rotating banner (with out requiring to refresh the page) where it does not have to load all at once. the dispalyed ad will be a button where we can click & go to a new URL

the reason is simple, as the ad increases, the 2 flash movie got so big that they are more than 1mb in size! :(
