[imgbox] Extraction error, site change (late 2017)

[Hrxn]

First, congratulations on 1.0.0 . Really good job! 😉

Imgbox is not working atm, caused by a site change, as confirmed by Google Web Search turning up issues for this site with other programs etc.

gallery-dl 1.0.0

Python 3.6.1 x64

Well, fuck me sideways, was just about to click on 'Submit', but then decided to try another URL..
http://imgbox.com/g/wg9TY0XSg7

And this seems to work. Oh my, even if something is broken, it has to be broken in an inconsistent manner. Obviously.

Can't tell why No. 3 is working. I think this is a rather old gallery, while the other examples are pretty new. Maybe the site change only applies to new galleries..

The other difference I can think of is the gallery title. The first two have a specific title, while no. 3 does not, only a generic 'Unnamed Gallery etc.pp.'..

Okay, probably not the title, but they definitely changed the URL scheme for the actual images..

The HTML:

Thank you.

… but they definitely changed the URL scheme for the actual images.

This seems to be the only site change that actually caused any problems here. Images in your first two galleries are hosted on https://images2.imgbox.com, while older(?) ones are hosted on https://i.imgbox.com, which is what was expected by gallery-dl.
