We're trying to improve the hard-copy printing of images, particularly  
for exams.   For one particular problem, if I do not set any size  
options, the latex code produces an image with a width of 142.2 mm and  
a height of 144 mm with the default single-column format.  If I use  
the TeXwidth option, like:
<img src="Figures/circleSym.gif" TeXwidth="50%"/>,
then the image is visibly flattened in the vertical direction, and  
looking at the latex code I see an image with a width of 90.17 mm and  
a height of 50.63 mm, which clearly destroys the aspect ratio.   
Further, If I use the single-column format, the image is visibly  
squashed in the horizontal direction, albeit much smaller.  This is  
very disturbing when asking a question about figure which should show  
a circular cross-section but that looks unquestionably elliptical.

If I try adding TeXheight="50%", the latex code generated is  
\includegraphics[width=90.17 mm,height=50% mm], which clearly won't  

I'm sure others have encountered this issue.  What is the  
preferred/accepted method for scaling images in LaTeX mode while  
properly preserving aspect ratios?
