Something very strange has happened. My images uses to link properly and now they are all messed up.
The default for an image used to be like this http://www.mysite.com/post url
Now I have noticed that some are like this
some are not linked
and a bunch are like this
I had changed my theme and regenerated thumbnails. It is a huge amount of work to go back and fix everything one by one - does anyone have any suggestions as to what I can do?
