public Image i1;
i1=getImage(getDocumentBase(),"dr1.gif");
g.drawImage(i1,300,50,400,400,this);

this is how i do it for all images put in the dame directory

same error occurs even if they are inside a jar file or loaded as parameters ...
i think its because there are too many?
please help

If the images are on the same server where the applet resides then it shouldn't be necessary to sign the applet or alter any policy files.

What do you mean by "they work fine" - are there circumstances under which the exception does not occur?
