Image size bug

When you copy and paste an image into the comments box from a website, the thumbnail on the edit page is fine same size as the others. But when you load the page its massive. However, if you save and then upload the image the size is fine. Slight bug.

I was editing this page 5 Pounds - Charles III (Buckingham Palace; Silver Proof) - United Kingdom – Numista

Thanks

Pictures, especially on catalog pages, should always be uploaded to the Numista server anyway and not just be links to other websites. We have no control over those and the image source could move to another address or be deleted entirely (link rot).

Im not talking about linking to the images. I'm talking about when I right click copy image and then paste it into the editor it displays in the editor the same size as the others, only when published does it go massive. Its not a link to the image.
