i use "gyazo", which is for those of you that don't know a very handytool that screenshots and auto hosts it to url. jD ends up downloading the screenshot without my consent when i wouldn't download it otherwise. just wondering how to stop this from happening.

edit: i just tested it and it didn't download this time for some reason. linkgrabber does pick it up though. maybe i'm just downloading it by accident. i guess to revise my question: how can i stop linkgrabber from detecting the gyazo url?

There are several ways to do this.

You can exclude the website by using the Link filter in Settings -> Basics -> User Interface -> Linkgrabber

add the following line :-
.*?gyazo\.com.*?

You can also stop grabbing jpegs, other types of pictures or http links :-
