A more complex method would be to create a loading script which contains a list of the files you want to load. Open the file, read the names, load the files, repeat until dones, close the script and carry on. This would allow you to add or subtract files as needed. You can make the script even more flexible by reading in the images IDs and other data as well. That way you're not locked into sequential file names, etc. Lots of room to play with that idea.

As an example, you can really go off the deep end if you want. Here is an sample VirMin file. It's a combination of game setup and level loading script. It loads the maps, models, props, game data, custom dice, critical hit tables, etc. for a tactical space ship war game. Using a different script, the game engine could load in a dungeon crawl scenario or a game of chess.
