Determine an Image

How can you determine an image file from another not-image?
In my app I must declare all images extension ?

? IsFileImageType( cFile )
This works only for the image types that FWH can display without freeimage.dll

I try with some image files and it return true only fot these files
png
bmp
emf
gif
jpg
tif


return false with these files

pbm
pcx
tga


Now I add these lines

IF UPPER( RIGHT( cFile, 3 ) ) == "TGA";
.OR. UPPER( RIGHT( cFile, 3 ) ) == "PCX" ;
.OR. UPPER( RIGHT( cFile, 3 ) ) == "PBM"
lFileImage:=.t.
ENDIF


and with freeimage I can show pcx tga but cannot show pbm
