I use Photobucket and I upload my picture there. Once I have it uploaded and into my Album(What ever you want to name it) I hover the mouse over the picture I want to show and a sub box will come up below it. Click on the second one down(Direct Link) and highlight it. Right click and copy & Paste it in between this: on the chip board. You can do that how ever many pictures you want to show. Will look like this below except put the ] after the first [pic right before the http::

If you want to show three pictures, place (type) each jpeg URL between "" like I did here:
[pichttp://www.antiquegamblingchips.com/crest/bison.jpg" BORDER=0>
[pichttp://www.antiquegamblingchips.com/pictures/arab.jpg" BORDER=0>
[pichttp://www.antiquegamblingchips.com/pictures/aguac4.jpg" BORDER=0>

Then when you preview it, you should see something like this:

Hope this makes sense and helps. If you want you can email me and I will try to help you more if I can. Take care & Have a great day, Mark
