Hey Dr. X errr I mean Beer. If by thumbnail you mean insert a small photo (or image) in the message box that enlarges when clicked. (sorry not good at technical names) Then click on post reply, scroll down to "manage attachments" click on that, It takes you to a screen with a browser, find the image, make sure that it is small enough (grumble grumble) and click the upload button, Browse, click and upload as many as you want, go "back" to post message box, input witty text, scroll down and hit send. Flippin' simple ain't it? Thank goodness for fifteen year olds .
