AlegroCart

I had an SSL certificate installed on my domain after installing Allegro cart. I went to the config and Shop Setup tab and clicked on Use SSL. If I browse to https instead of http, most of the images are then broken. What am I doing wrong? Should the entire site be SSL, or does the coding switch over to SSL only on pages that collect cc info? TIA for any help.

SSL is used if it has sense, e.g sensitive or private data are sent (account create etc.).
You have nothing to do, just to enable it. Everything else works automatically.
