In our web application we have List/Details and Edit pages
On the list page we show default image, and some other short information
On the edit page, we have a rich text editor and some other fields like title, valid date and etc.
Please note that rich text editor supports image uploading.
Now I have an idea, for keeping editing clear and minimal, to take the first image from rich text editor and show it on the main page. Is this something that is used in practice, or it is better to ask for an separate image?
