If your UI project does not have an App_GlobalResources folder you should right click it and choose Add > ADD ASP.NET Folder > App_GlobalResources
Then you should add SlideShowResources.resx to that folder and add strings for your resources.
Then in your post build event make sure to copy the .resx file(s) up to Web/App_GlobalResources
Hope it helps,
Joe
ps, next time one question per thread would be appreciated to keep the forums organized. This thread started out about jquery and ended about resource files.
