TIFF images are shown as blank when embedded in some web pages

They're bitmap TIFFs (just black and white), not RGB or greyscale.

They look fine on 10.5.8 with Safari 4.0.3. They also have non-square pixels. It could be a Quicktime problem, rather than a browser problem... but because I'm not using Snow Leopard or Quicktime X, I can't replicate the problem you're having.

 

Bit of an odd one, I would guess it is a Snow Leopard/Quicktime bug. IT affects both of my computers 10.6.1 and 10.6.2 on Opera, Safari and Firefox.

If you save the webpage as a html file with images and then load the file it doesn't work but if you use Quicklook to view the file you can see the picture.
