Accessing the attributes of an Asset field Specifically looking at these attributes http://d.pr/i/1ilbr

I can access Alt text by {{ entry.assetHandle.first().altText }} and similarly can do {{ entry.assetHandle.first().sourceUrl }} but Source Name continues to be elusive.

I'm confused as to whether this is an attribute or part of the AssetSourceModel? Although would assume attribute given it's editable.
I'm assuming that Alt Text (handle altText), Source Name (handle sourceName) and Source URL (handle sourceUrl are all plain text custom fields you've created on your Assets.

If so, you'd be able to access sourceUrl the same as the others:

{{ entry.assetHandle.first().sourceUrl }}


They definitely aren't attributes on Craft's AssetSourceModel.
