Comments - Felisaur

If you go to the original mod i based this on (Photo of a Loved One - Animated), scroll down to the first comment and there should be a guide written by the author explaining how to add an animated texture to the picture.

There is now a file called zzz_st_items_trash.xml and it should only edit the description of photo of a loved one. So the rest of the original file (st_items_trash.xml) should be as you made it.
You can translate the new file to Spanish and it should work.
