In Version 2 I was able to mod the gallery to show the URL of both the (large) thumbnail and the original (source) file. Both were listed below the picture. I did this so that if I wanted to link to a picture I could just copy and paste the URL of the size I wanted and be on my way (no right-click, propertied, copy/paste).
I can't seem to get the URL text to show in 3.0 when I try to mod the plog-functions file. Does anyone have the code for this? Additionally, I am now having to piggyback off of the "show details" area since I can't find nor add code below where the large thumbnail is generated.
