Had hoped to use this on a personal site of mine to have photo battles of horse pictures. Paid more for this extension than I've ever paid for a joomla extension. I had one problem after another which made me wonder if anyone else had ever even used it on a website. Support did help me with a few problems, but when it came to the last one - something that was a show-stopper for me. They refused to fix it unless I paid extra. The problem was that when photo battle displayed a pair of photos, the component allows users to vote for both photos in the pair. There is a setting that you can enter a number of days between votes, but it does not prevent them for voting for both the photos that are competing against each other. What good is a battle when users can vote for both the opponents? (My site is primarily used by young people and they were happily voting for both the photos in the pairs). This made the component virtually useless to me and since I had already paid a lot of money for it, I couldn't justify paying more to have them fix something that should have already been working. Refund was also refused.
There is a big difference between what you are calling here "problems" (meaning actually personal development requests) and real component issues. We tried to help you customizing the product further in order to suit your needs, but especially when you want new extended features, we simply cannot provide full details, as the time does not allow.
In our forum you can find all the free tweaks and further customizations that we have still provided you for free, although this aren't by far part of the product support!
On this custom requests, each developer is requesting to be paid, since further customizations are not part of the extensions support! We feel it's unjust to receive such review, which has nothing to do with the component itself, especially after trying to help you for free, as long as it was possible.
