How do I delete photos in Messages that fail to send?

I have photos I have tried to message to contacts, but they failed to go. Now those photos are caught in the message thread and I would like to delete them from the line. I don't wish to delete the message thread or the photo, just take it out of the thread . How can I do that?

Welcome to Android Central! Try long-pressing the unsuccessfully sent message and see if there is an option to delete.

I have the same problem, photos that did not get sent stuck in a message thread. A long press of the message thread deletes the message thread. I need to only remove the photo from the message thread. Is it possible?

I meant to long-press that unsent message, not the whole thread. So open up the thread and see what happens if you long-press that unsent message.
