My location has two servers, on one the graphs with file type png are created and displayed with no issue. The which was also displaying them as well, no longer does. Now the one of the png files is created but the other is not.
IMG SRC="/ibi_apps/WFServlet?&PG_Func=GETBINARY&PG_File=vppaadjx.png" USEMAP="#oxybkrfj0" BORDER=0 ALT=""


From above the vppaadjx.png is created, but not the oxybkrfj0.png. Can anyone help with this.

How are you creating the graphs? Was there a change in the code when the graphs stopped working? Please upload your codes for the 2 graphs.
