I recently noticed I can no longer download original images from 4chan. Every time I save an image, the hashes don't match and the downloaded file is always slightly smaller in size. This started happening a few months ago but I just noticed.
I tried using a different browser, different network, mobile, proxies, TOR, etc. Every time I get the same smaller, modified image that doesn't match what the original poster uploaded.
For example if somene posts this file on my pic, it's about 385 KB and has the hash CYgB58falgT/whack5h/NA==
https://desuarchive.org/_/search/image/CYgB58falgT_whack5h_NA/But if I download the file, I get euYAAxsC8GSKt5crzlv5lQ== 357 KB
I'm not very tech savvy but I read on /g/ that this might be related to how cloudflare handles files and that a work around would be to adding a "random query string" to the URL but I don't know.
This happens only with file extensions JPG/GIF/PNG, webms and mp4 files can be downloaded as normal and the hashes match.
Also I noticed that it seems desuarchive keeps fetching the original files posted without issues but not 4plebs, it also downloads a smaller modified image to the archive.
Can anyone help?
