>>815941like this maybe?
>/^([0-9]{13})|([a-z]{13})\.jpg$/im still catching all instances of 13 character all number filenames and a few mixed ones slip through
>>815915this one comes the closest to what im trying to do, it lets all instances of 13 character all number and all 'aaaaaaaaaaaaa' a-z filenames through but it still leaves a lot of instances of [spoiler:lit]r*ddit filenames which is what im trying to catch[/spoiler:lit]
since its random and numbers might show up in the 100s maybe i have to expand from 0-9 to something like 0-999? 1000+?
something like (.*[^0-9]|)(1000|[1-9]\d{0,2})([^0-9].*|) ?
thanks again for sticking with me
