ImageObject is the Schema.org type for an image file. It is used in two ways: as the value of image properties inside other types, such as an Article's image or an Organization's logo, and on its own to describe licensing details. Google uses the licensing properties to show a Licensable badge and license links in Google Images.
Image license metadata
For Google Images license details, Google requires contentUrl plus at least one of license, acquireLicensePage, creditText, creator or copyrightNotice. It accepts this either as structured data or as IPTC photo metadata embedded in the image file. If both exist and conflict, Google documents that it uses structured data.

}ImageObject inside other types
Most of the time an image property can take a plain URL. Using an ImageObject instead lets you add width, height and caption, which some parsers use and which is good practice for logos and article hero images. Google requires images in markup to be crawlable and indexable.
Original images and links
SaaS companies that publish original charts, diagrams and research visuals sometimes add license metadata with a credit and a page explaining reuse terms. This makes attribution terms clear to people who find the image in search. It does not prevent copying, and Google does not promise any traffic effect.
Example
Research report charts
Heathercombe, a subscription analytics vendor, publishes a yearly benchmark report with original charts. It adds ImageObject markup to each chart with creditText and a license page asking for a link back when reused, and embeds matching IPTC metadata in the files.
Common mistakes
License pages that say nothing
The license URL should lead to real terms. A generic homepage link is not useful.
Questions
No. Google Images indexes images without markup. ImageObject adds licensing details and context.
