When an image is posted here, it is auto-assigned a long filename. Q downloaded the file from here
Look at any post with an image - there are 2 links for each image
1) LEFT - auto-assigned filename by 8kun
link to it is file_store
2) RIGHT - filename the uploader has on their device
link to it is file_dl
There are times when Q uploads an image with a specific filename. That's why EVERY SINGLE ONE is listed on the spreadsheet - so you can search and compare or whatever.
