I think the part of the image you lose is the part below the baseline.
I think (someone feel free to correct me) the problem is that when
hyperlatex computes the image dimensions, it doesn't include the
depth. The relevant part of hyperlatex.sty is

\else
\def\@@@@image{\tex}
\def\endimage{}
\fi
One quick way to fix this is to add a blank line at the bottom of the
image enviroment when \makeimage is defined:
Change the
\def\endimage{\egroup
to
\def\endimage{\par~\egroup
Another (more proper?) way would be to put in the correct total height
to begin with. I don't know if there's a total height function
corresponding to the \ht height function, but the height and depth
could be added in a new register. Add the line
[EMAIL PROTECTED]
right after the
[EMAIL PROTECTED]@imagecount=10000
line. Then replace the definition of \endimage with
\def\endimage{\egroup
