-          The most common reason is that the file is not found because of an
-          empty or wrong baseDir setting, spelling errors in the file name, in
-          particular using the wrong case, or, if the image is retrieved over
-          HTTP, the image was not delivered because of security settings in the
-          server, missing cookies or other authorization information, or
-          because of server misconfigurations.  One way to check this is to
-          cut&amp;paste the source URL from the fo:external-graphic into the
-          Location field of a browser <strong>on the machine where the FOP
-          process will be running</strong>.

+Check the following:</p>
         <ul>
-          <li>
-            The graphic is too large to fit into the intended space.

-            Some image format subclasses can't be handled, try to convert the
-            graphic to a format subclass known to work. (Sorry, no list of
-            formats known to work)
-          </li>
-          <li>
-            Something else obscures the graphic, for example stuff from a
-            static content (very rare, but has happened).

+          <li>Security Problems (i.e. image was not delivered because FOP is not allowed to read the file).

       <p>Not all variants of JPEG are supported, especially those containing unusual color lookup tables and color profiles. If you have trouble with a JPEG image in FOP, try opening it with an image processing program (such as Photoshop or Gimp) and then saving it. Specifying 24-bit color output may also help.
