Also have you done the proxy mapping to image to appear correctly during preview?
Do we require proxy mappings to preview images...proxy mappings are generally require for redirections and if images are given appropriate relative paths then those should come fine by itself ...
Path to images should ideally be relative path, so in your case if your content is under "content/uk" and your images are under "content/uk/images"then "images/imagename.jpg" should be the path and you do not require proxy mapping
