AccessControlException!!!

[kjy112]

I'm writing a Picture Viewer applet to be used on the web.
It works fine when i first extended as a Frame, but when i incorporate it into an applet, it gives me AccessControlException.
here is the code that gives me problem:
/*i'm retriving all picture files from the pathName through the PictureFileFilter that implements the FilenameFilter and store into a listFile using the File.listFiles() method.*/

File myDIR = new File(pathName);
File[] listFiles = myDIR.listFiles(new PictureFileFilter());
-i've tried to use URL instead of getting the string of the path to post the image onto the JLabel, but that didn't help.
-i know it's a security issue with the applet security manager, but is there a way to get around it?
the following is my exception:
java.security.AccessControlException: access denied (java.io.FilePermission \pictures read);
-is there a way to change the filepermission of the security?
thank you all for reading this post.
any help would be greatly appreciated.
