WordPress gallery plug-in?

[Sly]

I'm playing around with Modula and not quite sure that it does what I want in the Premium version. The trouble I see with these free versions and the premium versions is you can't really get a full grasp of what the Premium versions are capable of without an actual trial?

Anyway, I want to do the following:
choose my own thumbnails
add alt text
slideshow
visitors can easily Tweet the image, would be ideal if I can customize the text
would be excellent if I could include text/link on the slideshow but not necessary

Anyone have a great gallery plug-in they are using that allows for this level of detail or something close to this? I have a list of several plug-ins that look good, I know I'll need a premium plug-in to get what I want eventually, but again it's very difficult to see what the Premium versions are actually capable of without getting to use them.

NextGen looks very close to being able to do everything above. Can't tell if I can create my own thumbnails or not.

Some of the magazine style themes can function if considering what is out there.
