My first question is regarding the gallery. In which file is the path to the album declared? I found the function "plogger_get_collection_url()" in collections.php but where is the function defined?
There is not one single location that lists the structure to the images directory. I just used InfoRapid Search and Replace to search for "plog-content/images" and it pulls up all instances in the list (showing 61 instances, but some instances are within comments). You can do something similar either with the program I listed or with any other multi-file search software.
