I recently purchased a new theme for my site and while in the process of testing it out before putting it live, I noticed that images display when individual posts are loaded, but not on the main index page or anything else that shows excerpts. Likewise, images in the sidebars are not loading either.
I upgraded to the newest version of Nextgen (I hadn't updated in a while) and after updating everything, I noticed the Plugin Check on the Nextgen options page. I ran the check and everything came back fine except for Check Theme Compatibility, which replied with the error in the title: "Missing the call to in your theme."
I assume adding this "call to" will fix the issue, but I'm fairly illiterate as to the workings of php. I've learned some small tweaks by trial and error, but I have no idea how to fix this or where to put said fix.
Any help would be greatly appreciated. If you need any further information from me to help resolve this, please let me know.
