Not when you're viewing on a Windows PC Roger, not unless you zoom in to make the whole page larger but that doesn't increase the photo itself. Even on your iPad you don't get any extra detail that way, it just starts to go blocky.
By uploading the original photo straight to the forum, the forum software shows a smaller photo but makes it clickable so that you can open the original and zoom in to see all the minute detail, which in theory is what you should be able to do even when the photos are held on a third-party website like Imgur.
I think the problem is that Paul has made a mistake somewhere and everything seems to work for him as it should because he's still logged into his Imgur account. However, if he was to log out and try it like any of us are, he would also get the "Zoinks! You've taken a wrong turn" message that we're seeing.
Of course, I can't make him rectify the situation but it's just so frustrating knowing that there is much more detail to be seen and not being able to get it.
