I do not like to use links to other sites, because sooner or later those sites vanish.
Here is a great example of how hieroglyphic translations could be rendered
I could not copy it to this post / e-mail, but if you go to their page:
They have two lines of hieroglyphs, click on Extract 1 you will see that line and if you move your mouse over the line, right to left, the translation appears...
Great !!! Try it
