First of all, I'm not entirely sure what the term is for a computer that only stands around and shows pictures, but I'm sure you've all encountered them at work, in stores and so on. Usually we notice them because they've bluescreened or they are showing some strange error message.
What I'm wondering is, is there a guide on how to set up a system like this in the best way? I'm thinking that custom distros (like XBMCbuntu for HTPCs) is a bit overkill for only showing slideshows, but surely there's some specialized software or some specific suitable configuration in some guide somewhere, even if the guide is very basic -- such as "Set up Debian Stable, install Gnome, write this in a script and run on boot to display your selection of images".
If anyone has any experience of setting something like this up, I could really benefit from some tips and tricks.
