Flash AS2 Thumbnail Grid resize rows and cols

Hey everyone,

I'm trying to create a XML thumbnail gallery that will re size with the stage. I want to have a XML file load the thumbnail but I want the thumbs to distribute based on how wide the movie clip that they are contained with is set to. For example if it's 500 wide they may be 5 thumbnails in the first row but if the stage is re sized and the container movie clip is squat to 300 there may only be 3 thumbnails on the first row....

Although it's a little hard to explain what I'm attempting I found another person asking the same question with an animated example.

Can you guys have a look at: http://board.flashkit.com/board/showthread.php?t=782139 and if anyone has any idea on how this could be accomplished in AS2, your help would be greatly appreciated.

Thanks!
