I don't recieve an error, I only get presented with the box to enter an URL for an image and don't get given a box to upload an image to a thread. I'm guessing I have just not configured it correctly yet, it's a new board. I'll check those options now. Thank you for your speedy response.
Ahhhhhh wait there. I can add an attachment by clicking the "upload a file" option. Though when I click the 'add image' icon I only get to enter a URL.
If I wanted to add 4 pictures to a thread, and upload the files, would I simply use the attachment option?
