I am new to ProcessWire and considering using it for a project. PW seems perfect for this project and so far I am very impressed with it. There will be several image galleries though that have hundreds of images in them. The images don't need a description or any other meta, so being able to mange them in a directory for each gallery seems much easier than trying to manage hundreds of images on a page. I am therefore interested in this approach and have managed to get http://www.responsivefilemanager.com/ working by creating a "galleries" directory at the root level of the site, putting the responsive file manager code there in one directory, and then letting it manage other directories for the galleries. Securing the file manager seems problematic though. It doesn't seem possibly to fully integrate this into the PW User/Login though. I've followed the Bootstrap instructions http://processwire.com/api/include/ and can tie into PW, but $user isn't populated (always "guest"). I can retrieve a user with $wire->users->get, but then isLoggedin() seems to always return true. I imagine this needs to be done in a Module to have more integration with PW and may look into doing that. I wanted to check first though to see if someone else has done this, or if it doesn't sound like a good idea at all, or other suggestions? Thanks!
