Ignore above warnings.

BTW, I just noticed, the situation with the uint16 count is corrected for the Photoshop tag. Declare count as uint32 instead.

I still think the general case should be uint32, instead of uint16, though, but this should not bother you.

Now I'm cooking...

uint32 give me:
  if (TIFFGetField(tif, TIFFTAG_PHOTOSHOP, &count, &data) == 0) {
          printf("No PhotoShop Tag found\n");

  printf("Size of PhotoShop Tag is %d bytes. Type is %d\n", count,

  return 0;

Which is the same size as reported by the wonderfull AsTiffTagviewer.

Thanx a lot.
