MyBB Hacks

I am writing some code that will display a random image from an xthread attachment.

the directories are placed under "uploads/xthreads_ul" and are prefixed ts_ so far I can not work out which forum each folder relates to
I have a folder  ts_1376 this relates to a forum with the fid of 22 can you tell me what the relationship is ?
I have the same problem with the images in the folder how do I work out what thread they are attached to ?
Regards Jim

The folders and filenames are completely unrelated to the forum they're attached to.  The folders are grouped by a timestamp factor, and filenames also include random components (to make guessing them difficult).
You need to read the database to get info on which forum/thread is associated with an attachment.
