Kenneth,
Look this over and give it another try.
Here are two links to video's that:
- Shows how to get a picture that is to large to upload resized so you can load.
- Shows how to upload the picture into a thread.
The first one shows how to size the picture, which seems to be a common problem uploading to the site and the second shows how to upload. The first one may help you?
They take time to load depending on your connection speed, so give it a moment to start up.
