I moved this thread from the testing 123 forum...more people will see it here!
Not sure why the image is not showing...if you want to delete and try again click where it says "edit photo". This will take you to a new screen where you can edit your comments, etc... There is a box at the bottom of this screen to check in order to delete the image. Check and click "submit"
Try the upload again and see if it works. You might want to try and reduce the file size a bit as well, by using a higher compression for the .jpg.
