Howdy grillmaster. First you have to find a location to upload your pictures. Recently we've found http://img12.imageshack.us/
to be a good place if your Internet service provider doesn't allocate you space under your contract. Image Shack is free and doesn't require registration. To include a picture use the BBCode commands [img]&[/img] it will look something like this: [*img]http://www.romineinc.com/users/upload/Bob-BQN-sm.png[*/img] (NOTE: Don't use the * asterisc in the command, I used it so it wouldn't display the picture and you could see the code).
A couple of tips:
Don't use spaces in the [img] command.
The "/" forward slash is very important. It ends the command. Make sure it's in the right place.
The path to your image is case-sensitive. Notice I have capital letters in mine. They have to be correct or it won't work.
If you just want to provide the link without the picture displaying in you message then you just type the URL link to it like: http://www.romineinc.com/users/upload/Bob-BQN-sm.png
and be sure to include the file name at the end.
Hope this helps!
