Before buying.
 

First:
With the package, do I get to download styles? I am interested in something a lot like www.dosual.com.
If i don't, do I have alternatives to reach my objective? I know just a little bit of programming, and nothing regarding css.

Second: I want attachments (images) to be water-marked, either with a word; or with a logo, such election shall be made by the user at the moment of uploading, or it could be an option in the control panel. Is this possible with any scripts?

Thanks, so far that's it.
