I have made a page that includes one album. This album contains 5 albums, and these each contain separate galleries. The 5 albums have space for a thumbnail but only 2 of them actually have it, and when I edit an album in manage albums, the select preview image box just says 'no image'. It does not have a dropdown, and no search function.
You can see what i mean here : http://www.escapeinsnowdonia.co.uk/blog/pictures/
What can I do to get thumbnails displayed on these other albums?!
Thanks in advance, Neil
