Hi Robert,
Basically, I added two separate custom codes, one to resolve the missing information, and the other to resolve some of the images.
The secod one should not be there, but I decided to leave it, as I noticed, that if I search for example ‘a3’ then the returned results had a missing image. By missing, I mean that the image was found, but pointing to a non-existent image file. So I checked each result to see if the results page actually has an image, or the problem is somewhere else. I found that the images were incorrect on the sub site, for example this post (fixed now), looked like this.
Now, that I see you fixed the sub-site images, I simply removed that second custom code. I believe the images should be correct on each result now.
