I have files that are named in the following manner:

   file.####.jpg (where #### is an hhmm timestamp [hour and minutes])

What's the best way to take the current hhmm timestamp and run backwards finding the previous 5 files, and checking whether they actually exist? There's a possibility one or more might not exist and rather than returning a blank value, I want to continue further back till I find the next.

   So for example, say I have:

   file 1122.jpg
   file 1121.jpg
   file 1119.jpg
   file 1117.jpg
   file 1116.jpg
   file 1114.jpg

Notice the gaps, 1120, 1118, and 1115 are missing. But I still want to return five, thus 1122, 1121, 1119, 1117, and 1116.

I thought of taking the current timestamp and loop five times, subtracting from it every time, but that's assuming all five are there. If one's missing then I only have four images.
