An update on my old posts with photos in.
Just over a week later from my first steps, and as far as I can see, all my old posts on here now link to photos on my own webspace, not horrible photobucket any more. I don't know how long I have spent on this - it was a few pleasant afternoons, sitting at the PC with most of my brain listening to music, and a little bit of it mechanically cutting, pasting, running the macro, pasting, posting.
Where people have quoted me, their quotes will still have the nasty photobucket ransom demand image, but the sense should be clear from the context.
To anyone else who has spent time and effort making this site a useful reference resource (as well as a sociable place to chat) please at least do step one - log in to photobucket and download all your own albums to your own PC - so you can restore images easily in future even if you only do so for one or two special posts or threads. (Apparently there is a Chrome extension which can download your albums for you if you prefer.)
And if photobucket's changes haven't reached your own account yet, count yourself lucky and take action while you still can.
If you do spot any images that I (and the forum search facility) have missed in any of my old posts, please let me know.
