Ok, if you'll look in your showimage.php file for this code:
Code:
Content visible to verified customers only.
And add this right above it:
Code:
Content visible to verified customers only.
Then that should take care of the problem.
I still can't believe that I didn't know that code was available, especially since it's been there since the beta's apparently. Oh well, I'm sure I'll make some good use of it now.
