You are still wanting to be in the stone age technology.  Please throw away the raster images of math and switch on to MathML. TeX4ht does an excellent job of converting LaTeX into MathML+XHTML which is what is needed to see your math documents on the web. As a proof of concept, I have put in an experimental chapter of my Professor's book, Cross Connections (which I am translating for him into MathML with TeX4ht) which is available at:

You need FireFox to view the documents. STIX fonts might be necessary to view MathML perfectly in FireFox.  I have created the documents without any tweaking in the source files and with a simple TeX4ht configuration of, say, less than 100 lines.
