Thing is, I've been using Photobucket for pretty much twelve years now and I don't know of any other free image hosting service that allows direct links to images. I know of Imgur and Imageshack, but I'm not sure if they allow you to paste image codes to forums. I've never used them. I'm not too concerned with finished artwork, since I have DA for that, and it's allowed me to direct link pretty much everything I wanted, but for WIPs I'm currently using my stash, and I don't want to cram it with several images or have to remove them from time to time. Besides, there's nothing I hate more than opening a thread in Rehearsals and seeing all images are broken.The free account does not allow any image linking or 3rd party image hosting.
I've searched the forum and found a similar thread, but it's from 2013, and maybe some of the alternatives have also changed their terms since then. So, any free hosts you use and like that allow hotlinking?
