Are all the files called file.xxxx.jpg or could they have other names such

They are all the same exact file name with the only difference being
the timestamp.
Alternatively, you could get the OS to do the work through an exec call to
something like 'ls *.????.jpg' or similar. The downside of this however is
that it is then OS dependent.
I thought of that too, but only because of the way the files are
stored. I completely forgot about one other catch... I thought about
it but my hands were too quick and I didn't type that paragraph in.
The files are stored as follows on the file system:
/.year/month/day/hour/file.hhmm.jpg (yes that dot preceding year
is correct)
So I can look right now and find /.2006/11/15/08/file.0846.jpg
Each /hour/ folder contains at most 60 files so in essence doing
either a scandir() or an exec call to ls wouldn't take that long.
However, I run into problems when I need to traverse to the previous
hour to find images.
Say I load up a file with timestamp 0802. I now need to find 0801,
0800, 0759, 0758, and 0757. The last three being in the previous
folder. Unless I run scandir() again the entire /day/ folder and sort,
I'd have to figure out how to go on about that.
Like I said, I completely forgot to write this piece of the puzzle
in my previous e-mail. I blame it on the lack of caffeine.
