    Can you ship the image with the applet in a jar? This would overcome the security exception and you can load the image from your app. If you must load it externally, you most likely will have to sign the applet (buy one or see Signed Applets - How to sign an applet (and get it to work) ).

    Loading the image from the app:

    URL url = getClass().getResource("/image.jpg");

    where the path of the image is inside your jar and relative to your class/package.

    while the first 2 ideas would work it would either make the html or the jar huge , as i need to be able to load over 5000 diffrent pics ( only 2 active at once depending on the choices made ) i have signed the applet but i'm still having problems loading pics with it . link to the applet

    i saw a way similar to that but decided to go with the full url instead
    do u know if this would work w/o needing signing ?
    URL url = new URL(//somthing that returned the applets url + /relative path& location of pic);

    the entire thing is setup as
    page 
       |
        --Applets
             |
             |--- .jar
              --- resources
                         | 
                          --- pics
                                 |
                                  --- pic type ( many of these )
                                            |
                                             --- pic ( about 30 in each above folder )

    Off the top of my head no. Is there any way to decrease the number of images? I briefly looked at the applet, didn't see any images show up but based upon the selections my guess is you could somehow overlay the colors onto a 'template' image which - if possible - could reduct the number of images considerably
