Lost photographs and the importance of backing up

I have been trying to find the photographs of the Wellington Pub and sign that I posted in the Moreton-in-Marsh thread a long time ago. I have looked everywhere but can't find them ? Have they been removed ? if so, could whoever it is that removes photographs from time to time please ask - inform the owner's first. I have had many of my posts over the years reduced-down which is fair-enough if I have over posted. But as I have just recently had two of my cards suddenly going blank I have lost about 2,600 images, so when I went to copy them from my post (Not all 2,600) and found they had also gone that means they are now lost for ever..
