A program that creates and alternates a selection of wallpapers based on the Pictures directory subfolders on your Linux.
A transition can be added when creating a folder (or moving an existing one there), in the pictures/or images , containing the right wallpapers inside. That is, not all directories containing only images are selected, you only need to add wallpapers resolution images, 1336x768 upwards. The addition will not be stantaneous. If there is already in a transition, adding a new wallpaper inside the folder, it does not transition to it to be directly possible, it takes a few days, hanging from the last update performed. Given new time to update the generated XML's , which are inside the directory containing the images, and have the name of the directory that is contained. Changing the name of the XML does not make the program stop using such, but it is irrelevant, because in the next update it the default name will be put again.
