[edit by Markpd - another option is ImgBB, here's a guide by PipSqueak for setting it up on an Iphone (but ImgBB is not just for Iphones).
If you only want to post a link to a Google photo, you can't simply copy and paste from the address bar, you'll need to click on the photo > share icon (3 dots with 2 lines at the top right, left most icon) > create link > create link, then copy and paste that link here. The forum will automatically make it a hyperlink (clickable), or you can hyperlink a word of your choice].
If you're wanting to share photos, you'll probably want to make an account on imgur. On the very top right of the main homepage (imgur.com/), click on "sign up".
On this page, enter a user name made up of letters and numbers only-- no spaces or special characters. As you can see, it will tell you if that exact user name is already in use. Enter a valid email address, and pick a password. When you're done, click "Next".
On the next page, click the box to prove you're not a spambot, then click "Register".
Ta-da! Congrats, you're an imgurian!
To upload an image, hover over your user name in the top right, and click "images" in the menu that appears.
From here, it tells you exactly how to upload an image.
I hope you can manage that step on your own, because I'm skipping it.
Well something funny is going on at Imgur at the moment. If you try to register a new account from the UK (at least) you get this message at the moment "We're sorry! Account sign-up is not possible in your region." I don't know if this problem is more widespread, but 3 of us from the UK get the same error message (I tried to register a 2nd account as a test).
How strange - perhaps they are at capacity currently for free accounts?
So, does anyone know of any other free image services that we can get processes documented for instead? Lets hope there are a few different ways to insert images on here otherwise we could lose a valuable part of the threads.
As per my post here in dec 2021 (and edit of the op) ImgBB was suggested by gerbilowner7. Pipsqueak reckons it's easier to use, and it appears to be more flexible too (although I still haven't tried it yet, lol. I've got loads of pics in Imgur).
Ah yes - I misread the top part in a hurry (after seeing your update pop up) saying 'another option is...' but if you want a 'new' account with imgur this won't work either then (alongside Photobucket)? I thought it was a thread recommending it still as it retained the older text, my mistake.
OK - I'll go look at the new site anyway to get myself aquianted with it incase imgur ever take further steps to rid themselves of freebie gerbil owners!!!
Yea that's right, Imgur (probably) won't work if you're in the UK, but I think it's still ok for other parts of the world atm? Hence leaving the guide as is, until we hear back otherwise. I did do a little bit of Googling about it, I don't recall finding issues outside of the UK, but it wasn't an extensive search. The 'another option' line is for ImgBB, not Imgur.
