Have you resized your photos that you have previously taken? The optimum size should be 640x480 pixels.
Have you changed the settings on your camera that you are using? What kind of camera are you using?
Do you go "advanced" when trying to post your pictures?
Do you select the photo and then click on upload?
Do you wait while the photo uploads and when it finishes click on close the window?
I know, lots of questions. When I first "relearned" the photo loading process after the "change", I also had a hard time. What I did was to write all of the steps down and kept the list at my computer. Why don't you post replies to the questions I asked on this thread and I will try to help you post your photos.
