I took off a couple of days and am catching up.
Looking at the drops 4437 and 4437 with George Floyd represented in the May 17, Obama Foundation post.
Did we verify if you have an image for a page set for Twitter Card, will that image change on Twitter if the page Twitter card images is changed?
This is a fair question. Can Twitter Card images on a web page be updated and that updated image be reflected on Twitter.
It look like they can.

Refreshing a Card in a Tweet
I updated my site meta tags, but my Tweet shows the old Card. How do I refresh the Card?
Our web crawlers re-index the Card tag information on your page roughly every week.
When testing and/or iterating on Cards, it is sometimes helpful to test updates on your timeline. It may be possible to use the following technique to refresh the cache with your most up-to-date changes of your page’s Card.
Add Card metadata to a page
Tweet URL to that page
Refresh your browser to view the Card contents on your timeline
Change Card metadata on the page
Take the same URL and runs it through bitly
Tweet the new bitly URL
Refresh your browser to view the updates
Additionally, you can create multiple bitly URLs to allow for repeat testing. For example, adding dummy parameters to the end of your URL (http://www.test.com/?x=test1) or a unique hash (http://www.test.com/#test1) will generally not affect the page contents, but will generate a unique bitly URL for each unique value of x.
My Card information now refreshes, but images are not updating. How do I get the images to refresh?/a>
Images referenced in a Card are also cached based on URL. This often causes images to not update when the above Card refresh technique is used.
To work-around this issue, you can add an extra parameter at the end of your image URL so that the Twitterbot treats the image as a unique URL and re-fetches the image.
For example:
<meta name="twitter:image" content="http://example.com/myimage.jpg?4362984378"></meta>
