Adds reverse search links above images on 8chan
Adds reverse search links above images on 8chan.
If the script is broken, please give me feedback on greasyfork with what is wrong and all the 8chan userscripts you are running and which browser and userscript extension you are using, I am unable to reproduce the few reported cases.
Settings:
The script now has settings to enable/disable services, available through your userscript extension.
While on 8chan, click the userscript extension's icon in your browser toolbar and you should see the "Settings" button below the userscript.
Services:
Note:
8chan.moe prevents hotlinking so passing the image URL to reverse search engines will result in errors.
For IQDB and SauceNao, a hidden form is created and the image uploaded cross-site, this works because their upload forms do not use a unique token.
For ascii2d and trace.moe, the image is sent across browser tabs using postMessage because they use a unique token.
For google, the image is uploaded to litterbox and then passed via URL because they do have unique tokens and Cross-Origin-Opener-Policy preventing postMessage.
