It could be that people are having problems with posting pictures - they might think their pictures will show on the post but then when they have a problem the pics don't show up. This msg board does NOT allow an upload from your PC to the message, like for instance Facebook does - the picture has to be on a web site somewhere and then you put the info for the picture in the msg post by clicking on the "image" button below the text window. I think sometimes people copy and paste their image link into there without removing the Http:// part that automatically shows up when you click on image. It always is a good idea to click on PREVIEW when you do a message with an image or a link, so you can see if the image worked.
As an example to get this PGCA logo I went to the PGCA web site, right clicked on the PGCA logo image, then clicked on Copy Image Location, then went back to the message board where I was typing the message, clicked on the image link at the bottom, cleared out the http:// and then right clicked on the box for image and selected paste - that put the URL for the PGCA logo image in there. I then clicked on the PREVIEW box and confirmed that worked. I then clicked on POST.
It would obviously be much easier to have the msg board do an "upload" from your PC but it just does not work that way, we cannot control that.
