I noticed an issue when trying to post a pic from a smart phone by using the image URL:
On a PC, the pic shows up as soon as you paste the URL, no need to press a submit button or anything like that (which is nice). But on my smart phone, that automation didnt work and because there was no submit button, I could not find a way to make this work at all. I had to wait until I was at a PC to fix it.
Im using Chrome on an (old) Galaxy S4.
