Hi,
first of all: thank you for your amazing plugin and sorry for my bad English. 🙂
Now I need a special version of your plugin, and I hope you will (want and can) help me.
I’m working on a site that can be seen only by logged in users. I need albums and subalbums where users can upload their pictures to. But every user could see and manage only their own pictures from the common album. It would be great if they could do this from frontend, and could upload pdf too.
Could you help me whit this? (Of course I would pay for this modification.)
