WordPress + WPMathPub — math publishing platform
WPMathPub is a WordPress plugin that renders mathematical expressions as static PNG images directly on the server. Authors place [pmath] shortcode tags anywhere in a post, page, or comment. The plugin processes the expression through PHPMathPublisher and saves the resulting PNG to a cache directory.
Because the output is a standard <img> tag, the math displays correctly everywhere WordPress content travels — no JavaScript required on the reader’s end.
Reader comments — two-way math conversation
WPMathPub enables [pmath] shortcodes inside WordPress comments. A reader can respond to a post using full mathematical notation and the equation renders as a PNG image — just like the author’s equations do.
This turns a WordPress post into a two-way math conversation. A physics teacher can post a problem, students reply with solutions using proper notation. A blogger shares a derivation, readers suggest corrections in math — not just words.
No other WordPress math plugin renders equations in comments out of the box.
RSS feed — static PNG works anywhere
Because WPMathPub renders equations as static PNG images rather than JavaScript-dependent HTML, math displays correctly everywhere WordPress content travels: RSS feed readers, email newsletters, feed aggregators, and syndication services.
JavaScript-based math renderers (MathJax, KaTeX) fail silently in most RSS readers and email clients. WPMathPub equations are just images — they work in Feedly, Thunderbird, email newsletters, and any other feed consumer regardless of JavaScript support.
Image URLs are now stable across plugin upgrades, so previously subscribed readers never see broken math after an update.
Education — students and professors
WPMathPub is well suited for educational WordPress sites where math notation is essential. Professors can publish lecture notes, problem sets, and derivations with properly rendered equations. Students can submit solutions and ask questions using [pmath] in comments.
The static PNG approach means equations appear correctly in every student’s RSS reader or email client regardless of their device or browser configuration.
As Cresswell & Speelman (2020) note, mathematics provides transferable skills found across educational institutions worldwide — WPMathPub makes those skills publishable and shareable on the open web.
Government — science and policy
Government agencies, research institutions, and science communicators increasingly use WordPress to publish technical content for public audiences. WPMathPub allows policy documents, scientific reports, and data analyses to include properly rendered mathematical notation without requiring readers to have special software.
Because output is static PNG, equations remain readable in official RSS feeds, press releases, and syndicated content distributed to news aggregators and partner sites.
Industry — engineering and R&D
Engineers and R&D teams use WordPress-based intranets, knowledge bases, and public technical blogs to document algorithms, signal processing techniques, control systems, and more. WPMathPub renders equations server-side so technical documentation displays correctly for all readers — from internal team members to external customers.
The [pmath] shortcode works in comments, enabling technical discussion threads where engineers can collaborate using mathematical notation directly in the post comments.
