I would like to create a gallery that displays thumbnails of my signatures and that has an enlarge ability when enlarged i would like a poll of somekind, and add like next page to the thumbnails.
And most important i would like to be able to add or remove the pics withoud changing the fla.

My question is as follow:
Is this possible ? ( i cant use like php or enything )
