V3 with thumbs scrolled Photo gallery with 80x80 not 40x40 thumbs problem

Hi I’ve been testing out the V3 with thumbs scrolled .fla from this topic

well basically i’ve been trying to modify it to accept images for the thumbs as 80x80 not 40x40 no matter how much modding i try to do (and i’m crap at actionscript verymuch a newbie) i can only stretch all the 40x40 images and the 80x80 images are oversized for the buttons?

should i be testing all the images as 80x80 or is there something i’m missing (all the images will be 80x80 in the end)

Cheers guys for any suggestions
