mass image scanner (2008)

scan_pics.php

<?php
//scan_pics.php
//Mass image scanner for URLs.

//Valid known prefixes: DSC, DSCN, DSCF, DSC_, DSC, IMG, IMG_, Photo, PIC
//Valid suffixes: .jpg, .png (etc, keep in mind on linux servers file names are case sensitive, so searching for .JPG, .PNG may be useful, but cameras usually save them as lowercase .jpg), _DSCN.jpg (in rare cases)
//For more suffixes or prefixes read up on http://en.wikipedia.org/wiki/Design_rule_for_Camera_File_system

//Optimal usage: /scan_pics.php?url=http://filesmelt.com/dl/&prefix=DSC&suffix=.jpg
//You must edit the URL to your own likings.
//In the demonstration it was used on this URL with the DSC prefix although it only finds one photo.

//Additional parameters: &start=0, &end=9999 (most cameras only go up to 9999 so there's no point in going higher)
//The additional parameters are also good for certain number scans, i.e. from 600 to 699, such as trying to find a set of photos.

//All files that don't exist will error, any files that are found will appear as normal images.
//The page will take extremely long to load on a normal 0-9999 scan, you'll only know what has loaded and what hasn't when it's done loading.
