Export to .jpg or .png

I volunteer for Distributed Proofreaders. Sometimes our Postprocessors would like to add .jpg or .png to their HTML. I don't see those option on the Export Menu any longer. It has PDF, however, they aren't used in our HTMLs any longer—only .jpg and .png.

Do you have a system for exporting to those? Or do we have to export to PDF and then convert to .jpg or .png?

Thanks in advance for all your help.
