url for post cover in image wall

Hi, I've just set a site that was http to https and am now getting some ocassional redirect loop errors.

Looking through the page source it seems that the only items that don't use either an https route or a relative url are the post cover images in the image wall module.

It may not have anything to do with the redirect error but am working through a list of things that could be causing the issue.

Here's the code with an added space after the www. The posts are sent via my clients email client so she doesn't login directly to the site.

</a>

Do you think that not having a relative url for the post cover could be an issue? Or is there a way to make the url relative to the root?

All thoughts welcome!
