Hi again Charles,
I'm guessing, but did you have spaces or some sort of punctuation marks in your picture's name. Something like, steam engine.jpg ? If so it has to be all one word to upload, like this, steamengine.jpg You can use . or - so you might use steam-engine.jpg
also, to avoid confusion, it is easiest if you use all lower case in your names. Once you have it on the site, from file manager on Yahoo, click on view, next to that image in the list. Then, at the top of your browser where it shows the web address, click once to highlight it. Now hold the control key and hit c (cntl c) . This will copy it. Now, when you want to show the link on this discussion board, instead of trying to accurately type all that, just click where you want it and hit control v. This will paste it in place without and mistakes. Hope this helps!
Steve
