I have written a M/TGP management script and would like to invite you all to check it out at the url below. Please feel free to email me with questions/comments at ap [at] apscripts.com.

What will most likely peak your interest is the flash-based in browser image upload and crop...kind of like photoshop in the browser (in a very limited sense). Anyway it is new action scripting in MX so you'll need flash 6 - but it is worth it! Upload a full size jpeg and try it out.
The sample site is here:

Bare with me while I get that together and incorporate some of the ad management features. Reply to thread or via email, I will be around.
*hope this isn't spammy enough to be spam*
