Aha! Thanks so much. I figured our what I was doing wrong!

Pictures on a thread:

I uploaded them to Picasaweb, there is a button right in Picasa that will do that for you, and you can choose the right size, for a forum you just want the smallest size.

Then you want the URL of the image, so right click on the image and 'copy image location' (I have a mac, it says something different on a PC but the same option should be there)

Then rather than using the link button, you need the image button (it looks like a photo of a mountain), and you paste the URL into the box that pops up. It will look like

[IMG ] URL [/IMG ] without the spaces.

Could you tell me how you added your Picassa screenshots to your reply on organizing files? I attempted to do the same thing but wasn't able to. Uploaded my screenshot to Flickr and added the URL link but the image didn't appear in my reply. Thanks for your help.
