Might be. It doesn't ring a bell but neither does the other contender (ILBM/IFF, ty Abigail) so I guess that info is gone from my brain forever, driven out by later memories of battles over whether GIF or JPG was better. (I do not remember what side I was on. Possibly Team TIFF out of contrariness.)

I mean tiff is just all the other image file formats in a trench coat so it’s absolutely the best in a sense

Right? Also I think I had a scanner by then so it was a good way to rub people's noses in it which, in honesty, I must confess would have been absolutely in character; Young Karen was a jerk.
