Mock

I want to upload an image. When I previewed my post, the picture was HUGE. I need to shrink it down, before I get yelled at for blowing people's margins. Can anyone help me with that? I have been to the help portion of the site, but it didn't do any good.

The image is a jpg.

A little outdated, as I dont think the attachment option still exists, does it Duchess?

JSMom posted the easiest way. But if you ever need to just resize for personal use, MS Paint will defo do the trick.
