Ugh! I do not see any way to fix this. I’ll try to explain.
The Stack theme is using a newly 2 year version of a script called
picturefill.js to show the images. Version 1.2 from what I can tell. Here’s a link to the script on your site from the theme:
Connections also uses
picturefill.js but it is much newer, version 2.1. The current version is 2.2. So I should update the version that comes with Connections. But that will not address the issue.
The version that comes with Connections is being used but is not compatible with the old HTML markup for images that was required to make version 1.2 work. Since is is not compatible, the script is not looking for it so it is not showing the images.
Actually… now I think about it, this incompatible markup means that both should be able to run fine together. The version that comes with the theme just needs to be force to be used too … I can do that, but I’ll need a temp admin account so I can login and make a small edit to the theme. You can send me the login details using the contact link at the bottom of the page. Please paste a link to this forum thread so I can relate the two. Thanks!
