I need to know how to make one of my print screens a jpg so I can attach it to a thread...

Please help.

Paste it into Paint (as per norm.)

Select File -> Save As - >
Then down below Save As Type drop down box - > select JPG (JPEG)
Select where you want to save it too (Desktop?)

Give it name like "Holy"

Save

Holy.jpg

paint is terrible to edit
if you have no other image editor download IRFANview its free
loads fast ,does a lot

Actually I hate Paint

But if we're talking 3rd party, I use faststone http://www.faststone.org/FSViewerDetail.htm
Give this freeware a go, you'll never look back.

I second Irfanview, can't imagine anything being better. I've been using Irfanview for as long as I can remember.
