gif highway shield transparency issues

[Mark Wright]

Try converting the shield from a transparant gif to a transparant png.
Perhaps transparancies are lost when converting between file types.

I previously had the Imagetype set to png24 because it displays my aerials really well.  Unless I can get the GIF to be transparent in png24 I don't think I want to switch to the GIF setting just for one symbol.  I have attached my highway shield gif.  I hope you can still help.

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.
