POST is irrelevant, because the images are accessed with GET, not POST.

If the images are tied to the page, either the URL for the image should
contain some function of the time, so that the correct version can
be regenerated, or the site should generate a temporary image file at
the same time as it generates the HTML, and include the URL to that,
temporary, file in the HTML.  Temporary files are a common tactic for
security by obscurity on software download and map sites, to stop people
redistributing the link to the underlying resource and bypassing the
HTML page and its advertising payload.
