Image Gallery, Upload Form, Watermark queries..

[abhimation]

Need a lot of help and suggestions here guys. Any help with anything will be really good.

My forum is about artists and their artworks so a big section of it is dedicated for them to post their artworks and for other to critic on them.

Now i am looking for to make their job bit easier, faster and interesting..

1) Can i create a form for them for adding in details about their artworks and to upload the images ?

Eg. Suppose its a photography section, when they click on that particular forum section, it should lead them to a form that asks them about the Photo caption, location, views and a way to explore image on their machine and upload that...

and that automatically creates a thread of their artwork with all the details in that section.

2) How can i add a watermark logo or my forum name in that uploaded image automatically ?

3) My forum sections already show thumbnail of the image inside thread in the forum homes, so how can i just show those thumbnails, userid and title in a gallery style.

4) OR should i just make use of a photo gallery application ? Which one would you recommend ?

5) I wish to allow my users for them to build their own portfolio page with their details from their profiles. Any suggestions for that ?

Anywhere you could suggest anything would be great.

Thanks a lot.

Cheers !
