Pictures are probably too big for this forum. I found you can resize them pretty easily in "PAINT" (or "PAINT-3D" in version 10) if you're using Windows. Just load 'em up in "PAINT" and immediately save them as ' ".jpg" images.b The resulting image should load. I am only belaboring this point because I want to see your pictures.
Another method for pictures is to use the 'Go Advanced' button and then the 'Manage Attachments' function. The picture files are treated as attachements and shown in your response. Using this approach, I've never needed to adjust the file size.
