Custom additional fields for albums and/or pictures

[GreenT]

Hi,

is there any way to add custom fields to albums and attachments (pictures) with a plugin?

I would like to attach albums to certain forums and for that purpose I need to save the forumid in the database.
In addition I would like to add more information to attachments/pictures (such as style, location etc.) - is there a way to do that?

I would appreciate any snippet of code to get me started.

Thank you for your help.

Marcus
