Being connected through facebook just means Steemit got some login details / token from FB, not that the entire infrastructure is now shared between the two sites.
As for posting images, it's just like anywhere else on the web - you pick file hosting service and stick with it. I stick to imgur, you can use imgsafe.org if you wanna do it incognito style.
Though you do have a point, for android the app is not working properly, and I afraid it makes people give up on posting. It's best to post from the web app on mobile, but do it like so:
- insert tags first, no caps.
- add text to post, might as well add title.
- click the insert image link, paste link, click go/ok/enter on soft keyboard.
- the picture will now be on the post, and you can press post to publish it.
I hope they improve the application and webapp to make it really bloglike.
Thanks for your reply. I know FB is just a way to sign up. Just so easy to put a picture on FB, i would like to see Steemit have the same easy format! I wont give up!
