Mike --To upload photos in a thread you can follow these guidelines.
Go to "post reply" (can not use quick reply)
scroll down to and click "manage attachments"
click "browse"
Find your file or picture file where they are stored on your computer.
click "open" when you have found the correct file.
click "upload" to upload pics no bigger than 70k for jpgs
The pics will upload, and you will see the results in the window when you see the file name.
Then, close this window by clicking "close window" at the bottom of that window.
Preview post to make sure that is what you wanted. Once you have done this a few times, this step is not necessary and can be eliminated.
If it is what you want, then click "submit reply".
Pictures can be no bigger than 70K. When you go into manage attachments there is a key chart which outlines the maximum picture size allowed for each document or photo type.
If your pictures are larger they need to be resized. There are many resizing programs out there. One recommended by CNET is Fast Stone Photo Resizer. This can be downloaded for free. Here is the link: http://www.faststone.org/FSResizerDetail.htm
