For posting on ZoneGFX, none of the allowed image hosting sites work

I'm attempting to make my first post, but it won't let me because none of the 3 allowed image hosting sites are working.

The first one, imagehostx.com, has a 404 on the sign up page so I cannot create an account there. The second one, bunkr.ru, is 403 when you try to go to the address. The third one allowed is listed in the pop-up on the upload page as as being "jpg4.su" but when you go to that it is actually "jpg6.su, so it does not accept that link. So it won't let me upload because of this.

Can I get some help??
