I was wondering how,using BackTrack,can I download files that can be viewed,if full address is specified,but cannot be listed?For example we have the following address:

example.org/somefile_6435.jpg

and let's say a hundred pictures with random addresses of the type:

example.org/somefile_****.jpg

It's time-consuming to manually try all the 10000 variations for a hundred files,so I guess there should be a script that can probe all the possible addresses and download the found files for me.I'm trying to overcome facebook privacy restrictions,given that I know the user's photos directory and the filenames,except for the last four digits,which as it seems to me are randomly generated.Thanks for the help!
