You would switch from ":results latex" to ":results raw", in which case
the latex will be inserted directly into the Org-mode buffer, and
org-mode's existing pretty display functionality may be used to view the
equations inline and should work for export to HTML as well.

Alternately, if you really want to get fancy you could use noweb
expansion (see the manual) to insert the results of the imaxima code
block into a latex code block, and then use the existing latex code
block functionality to convert the imaxima output to images of different
types depending on the export target [1].
