Hi,

what image  RGB ? GrayLevel ??? and what maximum point ?
The pixel coordinates of the highest gray values, since
the image data are usual 8 bit integer you will find
several points with the same highest gray level 255
And

img=Import["someImage.png"];
bm=img[[1,1]]

Position[bm, Max[Flatten[bm]]]

will do that.

Regards
   Jens
