Rather unlikely, at least for the majority of images sent. They are hosted on regular lemmy instances (the ones I got are on lemmings.world, lemmy.doesnotexist.club and lemmy.net.au), so unless the spammer has access to the server logs of those instances, they can’t use them for tracking.
What’s notable though is that the instance the photos are hosted on never match the sender’s instance, at least for me. So they probably upload them on one instance and copy the link into their spam script.
