one solution could probably be made using: glob(), sort() and/or filemtime().
btw: I assume your aware that the filenames are not very unique (i.e. twice a
day, everyday a given file will potentially be overwritten) and that this
is intentional

Are all the files called file..jpg or could they have other names such
as clouds.1123.jpg, field.2034.jpg etc?
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
($img_array);

Surely it would be simpler to store all this info in a database table? e.g.
id : int
created : timestamp
filename : varchar
Only files that actually existed would be in the DB, plus you could do all
your sorting on the 'created' timestamp column. Querying the DB should be
much simpler

Yup. I break out of the loop if $i reaches 10 for some weird reason.
