I know that MathJax can render LaTeX mathematical expressions as text.
Can MathJax render LaTeX math expressions as images? I can't find any information about this in the help documentation. If so, could you tell me the details? Thanks!
I assume you're asking whether MathJax can render math expression as images. Unfortunately, the answer is no: the only output formats are HTML-with-CSS and MathML, according to the documentation. Of course, you could try to convert the resulting HTML+CSS to an image using some other method/library.
You can configure MathJax to produce output using SVG (Scalable Vector Graphics) by: TeX-AMS-MML_SVG.js
