Is finding/replacing images possible?

[johnmcmillan]

I apologize if there's an easy to follow article that I've missed. I've run all of the usual suspect searches with no luck. I'm using node.js and I'm trying to open a PDF and replaces some images. Any help would be greatly appreciated.

Yes, it is possible.
