Could you please consider remove initial value "http://" string inside inputbox of http://danbooru.iqdb.org/ ?
I don't know if someone really type the link of image after "http://", but I find it much more convenience to just drag the image (which has image link on it) directly to the inputbox or right-click copy image's address then right-click paste on the inputbox.
And everytimes I do either of that, I have to drag and erase this "http://".
Please consider about it and sorry if my grammar has some flaws in it.
