When creating a new node, the imagecache image are not generated. After re-saving the node, then the imagecache image are created.

- Node with CCK image field
- Set as galleria with imagecache preset
- On creating new node & save: galleria "error, file not found" - the imagecache file is missing
- re-saving the node solves the problem

My point is, usually imagecache creates the images on first load (it checks whether the cached version exists, if not it creates it). With galleria this seems to fail...
