@ Asker et al Do let's keep always in mind that the actual verb here is 'referenced in' (from) — and I think that 'in' is crucial to getting the right meaning here — which I must admit I find unclear. Asker, I hope the rest of your context may give some clues?

Ti start with, what is this "it" that displayed them? The huge number of images involved seems to me to suggest this could not be a simple document for example, and I wonder if even anything like a PPT presentation could quite handle so much information — and the usefulness of doing so!

I have an inkling that 'referenced in' here specifically means 'references were given to all these images' — e.g. hyperlinks, etc. so that people would have to go and find them if they wanted to see them.

I have a feeliong this is not about 'referring to' things, nor yet about 'using them as references'; note the use of the specific verb 'referenced', which can have different meanings depending on whether we are talking in purely IT terms, or more generally.

I think before even attemmpting to answer this question, some clarification as to the exact meaning of the source text here would be immensely useful!
