I'm making a program that allows users to load their own images into it.  The plan is to have a user image folder and everything inside that folder is loaded into the program at setup().  The problem I'm having is that not knowing what the names of the images are, the only way I can get it to work is to force the users to rename their images tex1,tex2,tex3...ect.  Does anyone know a way for processing to read in the images without knowing what there names are ahead of time,such as scanning the folder?

Thanks PhiLho that solved one problem but in implementing the code I ran into another.  This might be a stupid question but I can't seem to get the relative pathname to work with the example.  This code works if I put in the absolute pathname leading to the image folder, but that kills the portability and usability of the code. I'm guessing there has to be an easy work around but I have very limited experience in this area.

//userimages is a directory in the data folder
String source= "userimages";
File dir= new File(source);
PImage srcImg[];
void setup(){
 srcImg=new PImage[100];
 size(500,500);
 if(dir.isDirectory()) {
   File[] fs= dir.listFiles();
   for(int i=0; i< fs.length; i++) {
     srcImg[i] =  loadImage(source+"/"+fs[i].getName());
   }
 }
}
