I think zoonar deserve to get some acknowledgements just for it's uploading process. Even i have problem with the media download manager software, usually i just need to deleted the program folder in windows and re-install it and okay.
But one thing can be improved is to show history of uploading, so most people knows what had been uploaded.
I also find out that the search engine is a bit different, let's say you want to look for 'running track', if your keywords are 'running', 'track' then it won't be in the results.
overall it is quite a nice website, and you can have a little shop to showcase your own photos.
