I've been working on a plugin to replace the images, because they are usually quite unattractive, slightly missized, not-transparent and uncoloured. I have something like 60 or so of the ligatures and rare glyphs to find sources for or write code to generate
... in any case i now have tool chain to generate a complete set of images from a few types of source. (it will not let me post a link) but its on github as wikihiero-image-generator
i'm wondering if this might help make progress in properly replacing the images.
i've used this to create a browser plugin (i can not yet post a link) but its on github as beautiful-hieroglyphs
i also currently have a prototype working from font and from svg although - the svg pipeline is awful though and invokes inkscape, and i have a few bugs to fix in the font pipeline
i've taken care about licenses although i want to follow up to ensure that every author down the chain did the same, but afaik everything here is under a GPLv3, GPL documentation or a less restrictive but compatible license.

someone mentioned noto sans before. i have generated images from this but there are a ton of problems. including tofu. they will not fix this tofu on ideological grounds. i'm not sure i want to recommend anyone use a product from people with that kind of attitude.

i'm also curious about the choices of images made for certain combinations, since they seem to be... in some case undesirable, and in a few look like spelling mistakes (although i am not very experienced in writing egyptian or hieroglyphs). the r next to the r, and the various cases of ir seem to use the wrong glyph D6 instead of D4
