gif highway shield transparency issues

[Clever, Max]

Thanks Chip,

that made it work.  I previously had it in png24.  But now with it set to GIF my aerial photos are not as good looking.  Do you know if there is a way to keep the quality of the png24 but get the transparency of the GIF setting?

Thanks again.

I had a similar problem until I change the IMAGETYPE for the map to:

IMAGETYPE GIF

Then when I defined the symbol color as transparent it worked.

I took out the TRANSPARENT line in the symbol file and the map still shows
the shield with a white canvas behind it.  I checked my image in a separate
HTML with a colored background just to make sure the image was transparent
and it was.  Is there a certain type of transparency that is necessary for
the image?  Is there some setting in the php or Map file that would not
allow transparent images to work?  I'm at my wits end.  I am using Mapserver
4.2. I really hope I'm not wasting peoples time with this question.
