We've created a slide show webpart in sharepoint 2010. Site authors can choose a folder (or subfolder) from any picture library located on the root site. The webpart will enumerate and display images from that folder.
Now, in our production environment, it turns out that only folders in picture libraries created by our administrator user works. Folders created by authors with less rights don't. Authors are still able to choose theese folders, but if you choose one created by non-administrators, the webpart code will not enumerate any of the pictures inside them.
Audience targeting is turned off and versioning is set to 'no versioning' on our test picture library. Any tips to why this happens are welcome.
