You can save as BMP very easily...

Dim pic as StdPicture

Set pic = LoadPicture("c:\test.GIF")

SavePicture pic, "c:\test.BMP"

Erik37. I already knew that one, but for some reason if you compile it to a DLL and regsvr32 it on a IIS server it doesn't work. I created an empty BMP file of 0 bytes.
That's why i'm looking for a thirth party DLL/routine.

Ark,
Seems nice DLL there i'mm check it out tomorrow.

By the way, i found what's wrong with the loadpicture / savepicture solution. That causes a read at the system color depth. Wich is in my case 16 (NT-webserver) so it totally ****s up the pics ...
