You can't predict what order the files will be presented in when you do a readdir -- you'll probably find they're in the same order you get when you do a raw 'ls' command with no sorting options, which depends on how the OS allocates space to store directory information (which almost certainly isn't in the order files are created!). To get them in the order you want, just sort them in PHP. The filename format you've chosen is also not good for sorting -- it may be ok for this year, but when you start creating files in 2004, you'll probably get an order like: 001_2003_01 001_2003_02 001_2004_01 001_2004_02 002_2003_01 002_2003_02 002_2004_01 002_2004_02 etc. (i.e. all files for January, subsorted by year, subsubsorted by image number; then files for February, by year, by image no.; then March, etc.). I would recommend a format more like yyyy_mm_nn (e.g. 2003_08_66 for 66th image in August 2003). Cheers!
