The attribution you are talking about is the alt
text of the image, which in Instant Images is the title
field. This is not image attribution.
In fact, this alt text on the Openverse images is not actually correct at all in terms of accessibility as it does not describe the photo one bit.
Please read about Alt text here – https://moz.com/learn/seo/alt-text
If you want an example of proper alt text, have a look at Unsplash feed.
2. Give the option to copy the attribution link, so we can add it to the page the image is on. Besides that you should show attribution requirements with every image.
It’s not up to me to decide how users want to attribute a photo. I cannot force anything to be displayed on the frontend of a website. I provide the option to add an attribution as a caption which can be copied and used wherever you like.
Do you see where you can add this attribution when using Instant Images? Just click the cog icon in the bottom right of each photo.
I appreciate your feedback.
