[mapserver-users] Reference obj & image file

[Vu Pham]

Thanks for everybody.
After using shp2img to create a gif file then converting to png  file
and applying the correct parameter, I could be able to display the
correct reference.

Thanks again,

Vu

Vu,
This must be happening because your gd doesn't support gif imgs.
Regarding your 2nd ques. I couldn't understand it so not able to answer.
Work around for 1st problem is to convert all gifs to pngs (which you
already did).
