Alt Text field for apostrophe-images

Create a new dedicated field for alt text for apostrophe-images. Currently the title or description field is being used for alt text, but improving the the schema to include a dedicated field for alt text would be good, as well as adding explicit help text to each field. To avoid any sort of BC break and confusion on previous implementations of these fields, we can create a feature flag (an option passed to the apostrophe-images module) that would activate these new fields.

Alt text would be made available the same way other image fields are here:

Brilliant! I will go back and give this a shot. Thanks for coming back to me so quickly on this!

@sachowdhary786 The question of this issue is how to add a dedicated alt text field. That will be part of Apostrophe 3.

There is no barrier to meeting this accessibility requirement in Apostrophe 2, but it does require you to choose the field you will use for alt text. The most common choice, I think, is description. You then would write your templates to use that field in the alt attribute. You could even add fall back options in the template so it could use other fields if someone leaves description blank.
