Re: Photos automatically added to Gallery
Welcome to Android Central! It might be an issue with the app's Lollipop compatibility. Apps like that should be designed to add a ".nomedia" file to the directory with all of the images, so that they don't get added automatically to your Gallery's database. If you can find the directory using a file explorer app, you could add your own blank file titled ".nomedia", which should prevent the phone's Media Scanner from adding those images to the Gallery.
