You can go a couple of ways. If you download the trial version of xat.com, it will let you resize and compress photos easily, and others have said that Picasso software from Google (freeware) is very good.

Otherwise, if you have free web hosting somewhere, post your pics there and use html to paste them right into your post like this:

Corgies rule
{{gwi:6914}}

Simply right click on your photo, click properties, then copy and paste the URL in the box in place of mine on this post. You can see my exact html by right clicking on my post and clicking "view source."

Good Luck!
