You can try with the following trick:

<script language="JavaScript" type="text/javascript">
        /* <![CDATA[ */
            if (AC_FL_RunContent == 0) {

                document.write("<img src='/path/to/image.png'>");

                } else {
    ...
                }
            /* ]]> */
        </script>

If you show an alert window with the text "This page requires AC_RunActiveContent.js." using the original page code the previous example should work.

If don't show the warning nor the flash content you should change the line

    if (AC_FL_RunContent == 0) { 

for

   if (typeof AC_FL_RunContent === 'undefined') {

The difference is that in the first piece of code the variable AC_FL_RunContent must be created to work properly. The second code checks if the variable actually exists.

You colud mix both methods.

Good luck.
