Yeah, that's pretty uncomfortable, because it's needed to use other services. At first I tried to use google photo, but if I post picture with link from there - photo disappear next day (or may be even not visible to others from the start). Next I tried vk.com and photoes from there is not disappear here, but it's pretty uncomfortable to use, because it's blocked in Ukraine and needed to use VPN to upload photo and if not to think that this network is piece of shit - it can be used. But as I see that noone reacted to this thread from the start of May - problem will not be fixed :(
Try imgbb.com it is the one that I always use, it gives you direct links to the image (which you can use here on pd.net or other pages to embed them anywhere in a post or in the comments) and even in BBCode and HTML code to embed it directly in your Website and / or Blog This is an example... On this page you decide if the image will be deleted after a certain time or if you want you can also keep it online permanently... Cheers! =D
