Help with feature box

Hey everyone,

Im trying to figure out how HGTV created their feature box, I would like to make one that is similar. - http://www.hgtv.com/

Im figuring that I can make one like this but with 5 feature spots and perhaps use numbers along the bottom instead of text. I think I can make it by setting up onLoad movie.swf actionscript on each part. So if there are 5 parts there would be 5 onLoads. Then each week I could make a different swf to feed into it. Exchange it out, but what about cacheing? I might have to change the filename due to cacheing issues. Also, Im not sure how I get a transition like that, I may have to experiment with this a bit.

Any suggestions?

Thanks in advance,

Jake Rutter
