Sounds like that's the one.
An <img> is inline and has vertical-align: baseline by default, so it
sits on the baseline, which means a gap underneath it for descenders in
the current font (tails of letters like g, y).
Firefox does a quirks-mode switch on this one. If you don't give it the
strict doctype, computed line height for a line containing only images
is the height of the highest image, which is aligned to the bottom of
the line box.
img {display: block;} is sometimes another solution.
