You can define attributes for Types custom Image fields, like alt, title, height, width, and description.
These attributes do not work when displaying the image fields on the front-end if your website is a multisite WordPress installation configured to have a custom upload directory (outside the wp-content directory).
Currently, there is no workaround for this issue.
Our developers are aware of the issue and will work on it as soon as possible.
