im wondering if the Open Graph Images need to be in a dedicated Folder or Picture Format ?

i have tried to upload via the normal media folder and choose the images (1600x632) in jpeg and or webp format.

So far so good it is accepting the image and storing but after a while no more picture and the link to the picture changes from images/2023/05/29/opengraph-shop.webp to

:"{\"src\":\"images\\/2023\\/05\\/29\\/opengraph-shop.webp\"}"

once this is automatically changed the open graph images are not working anymore.
