Ok, sooooo I've been making pictures with GIMP a long time, I have been that lucky that I haven't been in any need of changing the size of the pic or what I copypasted. Soooo..... as you all understand by the time you have been reading to this point "." I need someone to tell me how to resize the pics or copypasted items.

Sooo, can anyone do this for me?

Edit: I think this got into the wrong place, just forget it.
