Hi Rich,<br><br>Thanks... the same problem persists when i use 'mode=browse' and use the resulting image...<br><br>What might be related is the 'img' cgi control... can someone explain this to me? i read the documentation, but i don't get it... it doesn't show what value (if any)... here is the documentation entry:
<br><br><blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote"><dl class="docutils"><dt>IMG</dt><dd><p class="first">The name associated with the inline map image used to record user clicks.
What actually is passed are two variables, img.x and img.y.</p>
<p class="last">For the CGI Applications this is an essential variable, see the examples
for sample usage.</p>
</dd></dl></blockquote><br>there is no indication what type of value should be associated with it (like the other values in the reference indicate... like "ID [id-string]"), but it says it is essential and see the examples (which examples, i don't know...). can someone explain further how this control is used in a get statement issued to the mapserv binary?
