Missing Images from Post

Hi all,

This is a long shot, but I am updating a client’s site, working on a custom theme (rsminteriors.com) and I’m trying to add new items to the Press page. The ones that are there are constructed as Posts, but when I go to the Posts and view each one, I cannot see an image.

I conclude there is some other place where images are being uploaded and told to display with a caption in a grid on the Press page, but I cannot figure out how it was done.

I’ve tried looking in the code of the Post template, but I don’t know PHP. I tried uploading images to that post rather than to Media Library. I can’t seem to dissect how it’s done in other posts either.

I realize this is a custom theme and therefore difficult if not impossible to know, but is anyone out there who can suggest the first place to look?
