Links thumbnails breaking SSL

Hi folks

If you've been following my saga for a while, you'll know, that due to the nature of my site, we serve everything through TLS/SSL. In fact if the secure connection is impaired (broken/mixed SSL) components of my site will not work - a major issue.

I tracked the problem down to the sharing of links on the activity stream. When I link a site and EXCLUDE the thumbnail, the secure session remains intact when easySocial reloads to show the new entry in the stream. However, when I share a link and include a thumbnail served from an HTTP site, my secure session is broken. Thumbnails served from a HTTPS site do not break my session security.

I followed some threads (most notably here) that indicated that thumbnail caching would be included in ES 1.3. In the Links Application configuration in the ES dashboard I have set

"Serve image urls via internal proxy" to "YES"

but the sessions continue to break upon sharing HTTP sourced thumbnails.

Any help would be appreciated!

Thanks
