Done


edit:  Just kidding.  They bounced back, presumably cos they're too large (about 20 MB each or something -- I sent 2).

Duh . . . it was late last night.  I don't know why I didn't just throw the pictures into my drop box.  I'll do that when I get home later.

I used TIFF files too a long time ago (scanned film processed through Neatimage for noise removal) and sometimes had similar issues. Although I used 48 bit TIFFs.

Like Rayb says, (batch) saving it from Photoshop should probably repair the thumbnail.

Would this explain why the pictures also won't open in Windows Picture Viewer, though?

Not sure. I have had all kinds of compatibility problems with TIFF files though. Especially the ones with higher color depths. But then that was ages ago, you'd think that by now they'd got stuff to work properly.

The problem with TIFF is that it's a rather free format. Everybody adds their own specific parts too it and not everybody gets all the features implemented right.

If these things are 20MB, maybe it would be better to convert them to high quality jpegs anyway?

RayB:
JPEG is lossy. Just a warning. (Like i said, I recommend PNG or TGA. They will still reduce filesize since TIF is a bloated format to begin with).
