Leo,
You seem to have been on Windows server earlier. Your filenames contain spaces which get converted to %20 characters, for example, Filename "All Shook Up-- pa101.jpg" has been converted to "All%20Shook%20Up--%20pa101.jpg" which is a different file.
http://wizardartworks.co.uk/images/A...--%20pa101.jpg - the file is there, but not showing as per your links.
Please check your filenames, and remove any spaces in filenames, if possible. It will solve a lot of issues for you later.
