Tool for people who 'collect' images from all over the internet (or Telegram chats) and now want to find bigger versions of them or just e621 post links.
Uploading them one by one to iqdb.harry.lu would take so long so I created a tool right for this job!
It basically scans a directory, uploads images one by one and collects e621 post links.

Download

(script has autoupdate build-in, in case of future updates and fixes)

Github: https://github.com/jacklul/e621-Batch-Reverse-Search/

Requirements:

- Windows: Visual C++ 2012 Redistributable (x86) - download and install: https://www.microsoft.com/en-us/download/details.aspx?id=30679
- Linux: PHP library - "sudo apt-get install php-cli"

Basic usage:

- unzip it
- put all your images in 'images' folder
- run it with run.bat file (run.sh file on Linux)
- images with matched posts will be moved to 'found' folder, images that did not match will be moved to 'not found' folder
- after all is done check 'found' folder for 'links.html' file - open it with web browser, it will contain all the found links

Pushed an update, in case of error 'error.txt' file might contain the details.
Also check if that image file isn't exceeding something like 3-5MB.

 Trying md5 sum...Press ENTER key to continue...run.sh: 10: read: arg count

I'm not exactly sure what this means, but there's no kind of error log I can see telling me what's wrong. I'm using Lubuntu 16.04-LTS with

Also, sorry the error code got all squished... Damn dText formatting...

Tracked down this issue, package 'php-curl' is also required for this tool to work! Update pushed!

So I got it working, but I do wonder... is there a way that instead of having the shell script append the links to an HTML file so the user can manually click them, you can just have the script use curl to download the pictures from E621 directly? Would this break the e621 API rules?

Definitely doable, I doubt there is a rule about batch downloading, considering there are mass downloader tools there. :P

Apparently line 10 of run.sh is throwing a argument error... It doesn't break the script, but I removed it, and it just drops me back to linicks@tux-linux: ~$ when it's done doing it's thing.

Have you considered starting a GitHub repo for this project? This is actually pretty cool.

Try changing that line to

read -p "Press ENTER key to continue..." key

and see if that works.

Not sure about how legal is bundling packages with PHP runtime on Github...

Moved to Github: https://github.com/jacklul/e621-Batch-Reverse-Search/

There are going to be two updates, one which updates the update URL to Github API and clean up old files, second will be downloaded directly from Github.

For repository clarity version has been reset to 1.0.0.

20-03-2020 - updated for new e621 API

You can save an enormous amount of time by batching your md5 searches into groups of 100. the format is md5:abc123,483bbc,433,34 Basically it allows up to 100 items split by commas.

This is great, thanks.
