I have implemented a few bug fixes in the photo galleries.
The main bug I believe is fixed is the "searchstring is empty" error.
Anyone that was having a problem with getting a "searchstring" error, please clear your internet cache and cookies, then reboot your PC.
Then come back and try it again.
Please let me know if you are still getting that error after you have followed the above steps.
I have been unable to recreate the error myself, so I will need any feedback you can give me.
