This is just my own way, using a PC - I appreciate things might be different with different hardware!

Click on your username in top right corner. 

Click on “Images” – when you first start there will be no images to show. 

Click on “New Post” at top of page. 

Click on your chosen method of copying over photos – I only use a PC, so I click on “choose photo/video”. 

Select the image/photo that you want to add and double click on this – that photo will now be on Imgur. 

There will be a box below the image, named “Add image” – click on this to add another photo as before. 

Once you have added all the photos that you want to, go back to your username in the top right corner and, again, click on “Images” – whichever ones you have added will now show. 

Click on the image that you want to post on the forum. Once this photo comes up, there will be a choice of six “Copy” buttons on the right hand side – click the one alongside “B B Code”. 

Go to the post that you want to attach the photo to and right click your mouse – the “paste” option is all that should appear and click on this. The photo has now been attached to that post. 

Repeat the process for each photo that you want to add. Note, you don’t have to “submit” the thread for each individual photo – just submit once you have finished. 

The photos won’t actually show until you have submitted the post.
