Just noticed Imgur have recently updated their site yet again, so I've deleted much of what was posted previously here as it's now out of date.
You can still post pics onto Threetowners from imgur though - it's just a slightly different procedure from before - and you don't have to register or sign up to anything.
Go to https://imgur.com/ and click on 'New Post'
In the box that appears there's a line which reads .. 'Browse or drag images here' .. Clicking on Browse allows you to locate and choose the pic you want to upload from your PC simply by double clicking on its thumbnail. (I'd imagine the Drag and Drop function is fairly straightforward as well, but as I'm using a laptop without a mouse it can be a bit fiddly so I don't bother with that)
Your chosen photo then uploads to Imgur. If you then place your pointer arrow anywhere inside the pic you'll see some code top right inside it along with 'Copy' and a small 'V'.
If you only want to post a link to the pic on Threetowners, click on Copy then paste the code into your post.
If you want the actual photo itself to appear, place your pointer arrow on the small V and in the wee drop down menu that appears click on 'Get Share Links'
Then, in the box that appears Copy the code just below 'BBCode (forums)', paste it into your Threetowners post and Boab's yer Uncle.

I think it's best to resize any pics I'm going to post to 640 pixels wide or less before I upload them, as smaller files take far less time to upload.
