<DIV><SPAN class=343301814-21022008><FONT face=Arial color=#0000ff size=2>About
the temp files, I don't believe that you create temp files when MapServer is
acting as a WMS server. (Just like in mode=map). If MapServer is
acting as a WMS client, it stores a copy of the incoming image in the tmp
folder. Regardless, if the images aren't being stored in the directory
that you have defined as IMAGEPATH, don't worry about images hiding in the
cooling fins (or the Hello Kitty mouse pad...)</FONT></SPAN></DIV>

<DIV><FONT face=Arial>Hi,</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>2 items-- may be interconnected???</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>I recently set up a WMS mapserver using
MS4W. It works better than I have any right to expect, what with it
being my first real attempt; would have never gotten that far without help
from the list.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>During the setup phase, I was having the raster data
output as PNG files. Which looked awful. Which is because I was
used to seeing these aerial photos as 24 bit jpeg files. (the
documentation seems to indicate an 8-bit limit on png colors...?)</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>They would dutifully create a temporary png file in the
tmp folder.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Then, I changed my map file and my request URL to
indicate jpeg files, which works great. My observation is that my
mapserver is no longer storing temporary files. </FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>This also is good news -- because I don't have to delete
them -- but I am a little worried that they are building up somewhere else --
like in the cooling fins on my cpu, or in my power supply ;>)
</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Seriously, can someone explain about the apparent
8-bit limit in png files (is it true, will it change, etc.) and suggest where
the temp files are going? Below is the "WEB" section of my .map
file...</FONT></DIV>
