if i understand it right
using the above i have to manually define all the images

i would prefer reading the content of the directory 'on the fly'
there can be a lot of images

On the server, you can use Java (or whatever else you want). So, make
an RPC call from the client to the server to get the file names. You
could return a string array. On the server, it could be as easy as:

public String[] getImageNames() {
return new File('images').list();
}

Obviously, you would want to throw in some error checking and such.

HTH,
