The dreaded red x

[Serenity]

your image paths should be like this
fairytale/buttons
fairytale/statusicon
fairytale/attach

and so on

if your fairytale image folder is in the forum directory the images will show. it should have automatically once the images were uploaded to the server in the proper location and the xml file imported.
so your path to your images should be like this
mydomain.com/folderyourforumisinstalledin/fairytale/

sorry about the confusion. i will make sure to make clear instructions on the next release
