ALT attributes in formula image elements
I have a Blosxom plugin that recognizes <formula>...</formula> elements in my blog article files, interprets the contents as TeX, converts the results to a gif file, and then replaces the whole thing with an inline image tag to inline the gif file.

Today I fixed the plugin to leave the original TeX source code in the ALT attribute of the IMG tag. I should have done this in the first place.

${6\choose k}k! {N!\over \prod {i!}^{n_i}{n_i}!} \qquad \hbox{\rm where $k = \sum n_i$}$

If any people with vision impairments read my blog and have suggestions about how I could make it more accesible, I would be very grateful to hear them.
