I've had trouble with Picture Trail. Also, I don't how how to make images smaller: what you see is what you get.
When you use this method to transfer an image, you're actually linking directly to the original source. Usually this is not a problem, BUT... sometimes the original source doesn't want you to do this, and will cause a nasty image to appear instead of the image you THOUGHT you were getting.

Shirley, with your software system: right click your mouse on an image, choose "Properties" then highlight the "Address" and right click "Copy" (or "Cut", I think - not sure about "Cut"). Next, go to where you want the image, right click "Paste" and type [img] in front of address and [/img] after address. And PREVIEW, always PREVIEW!
