I am not sure to what point you can get to but this is what I had to do.
If you get to the point that you browse for you picture and hit the upload button, it should then say it is uploading. (for me it would not go beyond this point). I had to go in and resize my pictures to less than 550X300. If you have resizing software this should work. I have pixresizer and it works great. You can download it from the pixresizer website.
