Read the manual, don't see a solution right away so......
Suppose I make an installation with 32 Quads, name all the pictures /movies just pic-1, pic-2, pic-3 etc
Read the content from an external USB stick. Client can change content by inserting new USB stick with new content that uses the same names pic-1, pic-2, pic-3 etc....or even better, upload it in a map.
Would this be possible?
Thanks in advance, Barney
