I ran a computer store for many years starting in the dos days and wrote all my store programs in dbase. Got out of it about 1999 and am not up on todays stuff. I put slide shows in locations and presently go by the locations with a new directory on an SD card and change out the shows. I bought an android tablet with wifi capablity and mini hdmi port. I would like to install a tablet like this in the location connected to the internet. When it is turned on I would like for the tablet to run a slide show from the jpg files in a directory. I would like to be able to update that directory on the tablet via the internet. I spoke with someone from drop box and it sounded as like I could store files in different directories on drop box and have the tablet connect and download the new files.
