Ability to Change Extra Photos for Products when it is on a board already

Once the product is on a board, I get an error message when looking to delete extra photos of an item saying "the photos currently added to a product can't be removed because it is on a board." So, then I have to re-clip the same product to be able to add different extra photos to the item for clients to see. Often, the extra photos from websites I click to add to the product are very small images. I have to upload the photos of individually in order to get a bigger photo the client can see of an item.
