About your test module, it does not work after several install, only the message "no Images". As my english is very poor, I presume in your language "backspace" means "Return". For sure I am not able to understand your FAQ, certainly some more explanation are necessary for dummies like me. I meet similar troubles with gallery_Video, only Shreck movies seems to work and of course none of my own, or from other people registered on youtube. So I wait
Now you can download the updated and corrected version of the module. You can download the test module free.This version works correctly.
