Add actual image alt text to the Sandbox (Demo Objects).

[rosiel]

Overview of feature request

Accessibility is done in name only when we duplicate the node title into the image alt text field. That's already been read. That's not useful information. Sometimes it's the filename. That's also not useful.

When managing collections of images, we should encourage people to create actual alt text that summarizes the image. So let's do that in the Sandbox.

Current capabilities allow us to add image_alt_text in workbench. However this seems to apply only to the Original File.

Is there a way we can improve this so that it displays when the service file is displayed? For the mean time we could double-tag, but I wonder if the Islandora Image Viewer could maybe take alt text from a field on the node?

What kind of user is the feature intended for?

Screen reader users.

What inspired the request?

Accessibility consultants from Drupalcon following up with me.

What existing behavior do you want changed?

Lousy alt text

Any brand new behavior do you want to add to Islandora?

Good alt text.

Hi @rosiel if Workbench is only applying the alt text to the original file, we can change it to add it where necessary. I can open an issue on the wb queue if you want (I'll do some testing first) or if you want to, go ahead.

That won't affect any service files that are generated by derivatives (as far as I understand). I'd prefer a way to put alt text as part of the metadata. I'll pass this up to the MIG to see what they think.

Another suggestion - assuming there's always an "Original File", maybe its alt text field could be the source for the alt text for all derivatives instead of a node field?
