Is it preferable to have equations in LaTeX format instead of images, and if so, is it a desideratum to convert images to LaTeX when possible? I have been going through some older questions and converting equation images to LaTeX, but realized I should probably get a consensus on whether this is desired.
LaTeX can be read by screen-reader software used by people with impaired vision, & is often more legible in any case. It can also be searched, copied, & modifed. So it's a good thing you're doing, but make sure the posts are worth it—there'd be no point bumping a dozen five-year-old posts with no up-votes or answers to the site's front page.
