Gallery Builders - what software do you use?
 

Not to design/code, as I'm sure that will range from GIMP to Photoshop and Notepad to Dreamweaver... I mean for submission, regeneration with new thumbs in the same template, etc. etc. Any tools that rise above the others?

Without a doubt Chameleon Submitter and its line of products do EVERYTHING you need.

Its really easy to use.

Have a look at the video tutorials and you'll see for yourself
