A "web course?" I hope it's not about web development, because if so then
asking this question seems to disqualify you from teaching it. :-)

Options abound. You could use ImageMagick or GD, which are both accessible
from a wide variety of languages:
<http://www.imagemagick.org>
<http://www.libgd.org>
Regardless of the toolkit or language you use, the general approach will be
the same: You'd composite the image layers on the server, using the static
background, generated text, and uploaded image. The result would be a bitmap
that you would then compress to either GIF or JPEG to return to a browser.
None of that is at all relevant to HTML though - it's all done on the server,
which produces either image/gif or image/jpeg data in its response. You'd
refer to the server-side app that produces the image the same way you would
any other image, with an img element:
<img src="make_image.cgi?id=bar">
