Assuming you have mod_rewrite enabled in your Apache:

RewriteEngine On
RewriteBase /
RewriteRule ^images/([^\.]+)\.(jpe?g|png) /$1.html  [QSA,L]

Edit: as noticed by Wh1T3h4Ck5, QSA (Query String Append) flag would be optional, as well as L (Last) would depend on the context and other rules present. Please, read about RewriteRule flags for more information.

This is not an optimal solution for a large number of images, but it seemed to fit OP's case.
