Using XOOPS 2.0.14

Module: Newbb2

I am trying to get newbb to allow me to upload jpegs.

Whenever I try to upload I get a message that says:

Unknown filetype rejected
MIME type not allowed: image/jpeg

I have gone through the other forums and beleive that I need to edit the allowable extensions somewhere to include .jpg

Thats all well and good, but I can figure out where to do it.

Please tell me step by step from inside the Control Panel if you know.... Thanks a whole lot!
