The image is not enlarging for me however I can still make them out from the image in the 3rd row the 2nd and 3rd images from the left, given their age they couldn't have been scraped. Apologies if I made it sound as though you did that specifically. Given the nature of fractals similarities make sense as it is mostly math but those 2 specifically look too similar and only those.

They might look similar to you, I haven't seen your fractals so I can't be any judge of that. What I can be a judge of is whether they are fractals I generated, right on my computer, which they very much are. Here is a video where I have opened one of the fractals you picked out in Chaotica, I navigate around it, change some random parameters, and have a whole different look at the end. This would literally be impossible to do if I had taken the image off of wherever you had it displayed. If I really have to do this for the other one, I will, though I'd prefer not to waste the hour or so of it takes to let it all render out to begin with, create the video, edit, upload etc.
I did not take your fractals.
