Thank you for the feedback.
I'm sorry but the gallery template will not be finished before the end of the month. At the moment it is not stable and not secure! Sorry, I will not release any source code, the template is connected with complete new functions of jVoteSystem, you can't use it with older versions. I'm on a trip next week therefore I've no time to work on it, sorry.
I can't post a workaround because an upload function is complex and it is not easy to implement it.
The fatal error you described is caused by an endless loop of error messages. I'm not sure if this bug is caused by jVoteSystem, please start further tests. (Next time, create an own topic for the memory error but don't just repost your message containing a response to the image topic. Thanks!)
Best Regards,
Johannes Meßmer
