The easiest way I've found and you'll enjoy it.

Go to www.photobucket.com and open a free account.

Upload your pictures per their instructions, easy to do.

Click the Direct Link (2nd one down in a list of 4 under your photo).

It copies automatically.

Come here, click this icon: In your post tool bar. A window will open.

Right click in the window and click paste. Be sure that the original http:// is removed when doing this. Click okay,

Your picture will show.

(you can shrink your photos on Photobucket if it's too large)
