The problem is that Dropbox no longer allows for image hosting on the public folder. I still have them, but I realised it would take me weeks to reupload and edit every single image URL in the thread.
To be honest, and considering I no longer make skins, nor partake in this community, I decided to not go through with it. The download links to the skins still work (2nd mirrors, that is), and that's enough for me.
Sorry, guys.
