Asset Alt Text for Silverstripe 4

Adds an alternative text field to Image assets, so that you don't need to use the image Title field (which would typically be more succinct than useful alt text).

As a bonus feature, when adding an image to an HTMLEditorField, the alt text field gets pre-filled with any asset alt text.

Usage

Install via composer composer require purplespider/asset-alt-text

dev/build

Go to the Files and select an image to see the new field:

To make use of the alt text value in your templates, just use $AltText. e.g.:

<% with BannerImage %>
    <img src="$URL" width="$Width" height="$Height" alt="$AltText" />
<% end_with %>
