I've found several issues with Cel_PhotoPopup version 4.1.002 on vBulletin v4.1.10. Basically class methods/variables are being called without first attaching them to the $this-> instance.

In cel_pp_class_photopost.php, On or about Line 192 (very near end of file):

Was: $img['med'] = $img['orig'];
Fixed: $this->img['med'] = $this->img['orig'];

In cel_pp_class.php, On or about Line 109 (part of function set_choice_by_get()):

Was: $get_album = FALSE;
Fixed: $this->get_album = FALSE;

While I could locate the cause of the above issues and correct them, there is another issue that I have had to make a real hack of a fix for because I can not identify what is causing the page to generate an Error 500 (Server Error) unless at least a single byte is printed by a certain point in photo_popup.php. Around line 204 I had to add the following line of code: echo chr(0); in order to prevent the Server Error 500. With that single null byte printed to the browser HTTP headers are sent and everything works as it should (save for the preceding code fixes), but without nothing is *ever* sent to the browser and the server throws a 500 Server Error and PHP logs the error as "premature end of script headers".

I can not locate anything site specific (like Apache or PHP configurations) that would cause a timeout to occur if headers were not sent in under 1-2 seconds (about the longest possible wait) but it nonetheless behaves a lot like a timeout condition and it is 100% repeatable with absolute certainty -- if at least one byte is not sent to the browser (to trigger PHP sending the headers) by a certain point in the PHP code a 500 Server Error will occur each and every time.

Despite my best efforts, I have not been able to figure out why this hack is necessary to make things work.

If these issues have already been reported and fixed, please accept my apologies. I wanted to report my findings so as to ensure that you were aware of the issues I found so that the fixes could be incorporated into the next official release.

Thank you for your time and efforts in this regard.
