modify gallery script to attach .txt description to each images

hello

This script basically scan a folder for pictures so someone can just drop this php in a folder filled with picture to get a picture gallery automatically.

i’m trying to modify this script so when it return the name of the images, it get a description for the image from a text file of the same name (or xml or whatever) so that description can go in the <title> tag of the picture in the gallery.

so that you have in the folder
1.jpg = picture
1.txt = description that will go in the <title> tag

I’m very new at this and i’m afraid i can’t figure it out.

Please help me!

ps: yes i’m a beginner; but doing something about it ?
