PictShare VS libvips

I guess they had a system that required humans to confirm the validity or so.

I had a similar problem when I realized someone put up CSAM (Children sexual abuse material) on my public demo of my CDN called PictShare [1].

I didn't want to look through all of these images so I built a Raspberry Pi with a Neural compute stick [2] that used an AI model trained by yahoo to filter out "nudity" images and I put them in an encrypted ZIP file along with the access logs and sent them to Interpol.

This lead to the arrest of a teacher here in Austria so I'm glad I could do my part.

This even lead to a BBC article about my system [3]

If all you need is to just host pics and videos for reaction images, not albums or other metadata, Pictshare should do the hosting part well, and something like Syncthing could be used to copy files from/to the sharing directory. It's one of the solutions i considered to migrate away from using Imgur for this, but veered away from it since i do use albums with metadata too, for your case it wouldn't matter

PictShare

Reminds me a lot of pictshare

Interesting approach! I also made a project many years ago (still maintained though) that does something like that (also on docker hub). Basically it's a simple self-hosted image hoster where you can upload videos and images and you can resize them on the fly by changing the URL.

Image hosting. Not "Photo Gallery", not "Photography Showcase". Hosting pics to use all over the net. On Imgur i upload an image, a gif or even a short mp4 with sound, it will happily accept it, then give me the ability to quickly link directly to the image (not to the "Page of the Image", but to the direct image, gif or video itself). I can easily upload something and have it ready to be used anywhere, like here. Most image hosting solutions are poorly optimized for this as they're solving a different problem (replacing Flicker/Google Photos/Instagram/etc.). The one I've found that's by far the closest to fulfill this requirement is Pictshare, which is pretty much built for this, but lacks the second big requirement:

Can confirm. I had a public demo of my open source image hosting solution [1] (where you can resize images and videos by just entering a different URL) up for years without problems, until idiots started uploading CSAM (Children sexual abuse material).

Luckily I found out before law enforcement did [2] so I proactively talked to my federal bureau for months generating Excel sheets of IPs and access times and devices and countries. I didn't see many of the images myself, basically just looked at one upload per IP which was like three in total and forwarded all uploads of that IP to the police but man.. what the hell is wrong with people. 4 digit number of uploads of CSAM.

After some research, I found libvips, a demand-driven, horizontally threaded image processing library. It is designed to run quickly while using as little as memory as possible.

Sharp is a fast and efficient image optimization Node.js module that makes use of the native libvips library.

h2non/bimg can handle both if the underlying libvips is compiled with support for both formats.

if you're using linux (which it doesn't seem so) there's also vispdisp https://github.com/jcupitt/vipsdisp which is based on https://github.com/libvips/libvips which will likely take over how images are decoded in the future for everything, at least methodology wise.

The magic happens by way of a library called Libvips, which contains an ultra-high-speed low-memory image resizer.

imagor uses one of the most efficient image processing library libvips. It is typically 4-8x faster than using the quickest ImageMagick and GraphicsMagick settings.

Try the solutions here: https://github.com/libvips/libvips/issues/2479

in that case maybe take a look at https://github.com/libvips/libvips

libvips v8.6+ or ImageMagick for image analysis and transformations
