Thanks for the reply. I am quite happy with a Jpeg automatically producing a colour table and have been using PaletteIndex on my current project like a good Boy Scout. I am just trying to correct my understanding. Incidentally, TJpegImage only produces a palette if the line

DIBNeeded:= True;

is added. It then produces a palette of index 0 to 235 grays and 236 to 255 indeterminate, which is curious. TDibGraphic produces a colour table with 256 greys very satisfactorily.

The nagging question is how does it differentiate between a "Gray" image and a very desaturated colour image. Anyway, I can live without an answer <g>.

Best wishes,
