<DIV><SPAN class=623035719-07112008><FONT face=Arial color=#0000ff size=2>The
image is an ECW but JPG acts the same way. My question is why does
transparency come into play when I do not want to see under the image, I want to
see beyond the extent of the image. For example the image is 1 mile by 1
mile and it still covers up the whole county. Is that because the
mapserver still thinks the image is county-wide?</FONT></SPAN></DIV>

<DIV>What type of layer is it?<BR><BR>If it's raster it's a little harder to
deal with because it's probably being served as a JPEG and JPEG's don't
support transparency.<BR><BR>If it's a GIF then it's pretty easy to just set
the image as transparent, so if there isn't any data it shouldn't show
up.<BR></DIV>

<DIV><SPAN class=113060417-07112008><FONT face=Arial size=2>Hope to have
better luck with this question.. Does anyone know how I can keep an
image that covers only a city from covering up another image below it that
covers the entire county? The extent doesn't seem to work for me in the
mapfile.</FONT></SPAN></DIV>
