Content images receive AI-generated descriptive alt text; decorative images (icons, spacers, toggles) receive alt="" per WCAG best practice. Also adds Image Descriptions section to the accessibility page, and fixes Pandoc Lua writers to output alt attributes. 67 files, covering help docs, news archive, ENCODE pages, portal pages, and session examples. refs #37254 diff --git src/hg/htdocs/goldenPath/help/genomeEuro.html src/hg/htdocs/goldenPath/help/genomeEuro.html index 80d89461e0b..ebd2116e55f 100755 --- src/hg/htdocs/goldenPath/help/genomeEuro.html +++ src/hg/htdocs/goldenPath/help/genomeEuro.html @@ -22,31 +22,31 @@ notification at the top of the window that they have been redirected to the more geographically appropriate server.

After the initial activation of genome-euro, however, the Saved Sessions between the two servers began to diverge. New Saved Sessions or modifications to existing Saved Sessions are NOT copied from one server to the other, so a new Saved Session created on either server will NOT be available on the other. This is also the case on genome-asia (activated in 2016). Saved Sessions can be moved from one server to the other by saving them to a file and reloading the file using "Save current settings to a local file:" and
