I'm trying to add images to new product range. Per support I've uploaded the files via FTP into their corresponding small/med/lrg directories but my site is not calling the images. They are all correctly named and in the correct folder but not showing up on the site. What do I do next?

Also is there a way to preveiw the whole page without having to go live for a second while you review your changes?

Thanks in advance,
Michelle
