Then the image files should be in the same directory (or in its
images/ subdirectory, but that would need to be coordinated with the
package developers).

How do we generate these HTML files from the Texinfo sources?

So we have the HTML docs in two places?  Why two?  And why do I see
both https://elpa.gnu.org/packages/doc/compat.html and
https://elpa.gnu.org/packages/doc/compat/compat.html?

In any case, what I propose is to have the image files right near the
HTML files which reference them.
