Is it possible in Site Builder how do I show the latest images posted OR commented on?
Using Jamroom
The way the {jrCore_list} function works is it retrieves information stored in the modules datastore. One limit it has is that it needs you to select which datastore to retrieve the information from.
Images are stored in the Gallery datastore, while comments are stored in the Comments datastore. This makes it difficult to combine them into a single search.
From memory, I can remember setting up a system which listened for new comments being added to a datastore item and updated the _updated key for that item.
That again as an example to illustrate the concept: When a new comment gets added to a gallery image item, that gallery image item has its _updated time updated.
So its possible to do, but suspect it would require a module to behave like that. Easier would be to have 2 lists. "Latest images" and "Latest Comments"
Another option is to look at the "Item List (combined)" Site Builder widget provided by the "Seamless" module, then order by _updated on the Gallery and Comment modules. That would provide a list ordered by updated time, but would show a gallery image when it was a gallery, or a comment list item when it was a comment.
