Yes, Joel. You definitely can. Only issue I found it my pictures are usually too big and I have to resize them to get them to upload. I found it easiest to open a second window to the board, go to the file upload link at the top of the page, upload the picture and then cut and paste the link into the box below in the post. Make sure to delet the http:// that is already in the box if you cut and paste it in though or it will be there twice and not come up.
