please move if this is in the wrong place, I am hosting it on apache2triad which is apache with python php mysql xmail etc. I have a folder in htdocs called screens where I can place screenshots from the computer, and I dont want to change the script every time I get more pictures, is there a script to display all the pictures in the folder?

Sure. You can do a script to read the image files from that folder and display them. Check
