When I closed my account, it didn't disappear immediately. Your new link and any old ones may not work in a few days.
It is possible. I used it for both my good shots and hand drawn examples, desktop captures, etc. Since you can upload images here now I made a donation. I'd rather give my money to POTN than that mess. I also joined FM for that reason so I don't really need it. If I do need a reference to a image of a page from the camera manual, etc I just cut and paste as I know where everything is there.
I am trying a site called lensdump but not very much right now as I'm not sure about them. Free for now but who knows. Only reason is some sites that I upload to do not display at high rez.
Signing up with the Adobe plan you get free website using Portfolio so I cancelled my Zenfolio account. I have made some adjustments recently
