i need a little help in figuring out how to create this effect i’m going for.
i have a gallery of thumbnails on a page that have been cropped down just show the top left corner. what i would like to happen is when the viewer mouses over the thumbnail, it expands from the top left corner into the full image.
i’m not very familiar with flash or as3, and can really only figure out tweens 
i’d appreciate any help.
