I've found a few inquiries about this in the past few years, but all have gone unanswered, so I'm trying myself in the hopes that there's an answer now?
Even if a tumblr page/post is deleted, the images stay on the servers. You can directly access them if you know the url. The urls are mostly randomized, but the last few characters are common to the blog it's posted from.
For example:
https://64.media.tumblr.com/a3700873ceec020232ca5a4553e36b89/tumblr_n7bwnfhjB01qcn6kso1_1280.jpg
https://64.media.tumblr.com/7d02f88696690f73d2d5eb1425ff0a67/tumblr_n1maj0MTaY1qcn6kso3_1280.jpg
So "1qcn6kso" seems to be the url for my old tumblr.
How might I query the tumblr servers to find or download every image they have that includes "1qcn6kso" in the file name?
Or is there a fully comprehensive internet image search engine that would spit out the results? It's crazy to me that I can't use a search engine to search tumblr.com for "*1qcn6kso1_1280.jpg" and get results.
(I'm just using my old tumblr as an example, that's not the only one I'm looking to scrape.)
I've tried looking through github, but it's not clear to me that any of the scrapers do what I'm looking for.
