I'm trying to publish raster data as in image service. I've found a link with instructions on how to do this here. I'm able to get through step 3 just fine and verify my folder data source, but when it says to navigate and right-click the dataset, I have no idea where the dataset is supposed to be showing up. Registering a data store doesn't seem to affect what shows up inside of ArcCatalog, so I don't know where I'm supposed to navigate to the dataset from.
Any help would be appreciated!
