Unfortunately, any time you share a carousel post the image or video within it will never be deleted.
The only way to delete an image in a carousel is to delete the whole post.

In addition, adding a photo to a Facebook group album is really simple and you can remove it at any time. Click on “show people” in the top left-hand corner of your screen and then choose the name of your friend’s group album. This will open up all photos available for that particular group album. Any photo within there has an option to be deleted (directly below).

Tap the photos you want to edit with filters, and they will automatically be applied to all of the selected photos. To edit a photo or video individually, tap on it and select your desired filter.

We’ve all seen videos that zoom in too close on people’s faces — maybe a couple is dancing awkwardly at an outdoor concert and suddenly we’re nose-to-nose with them! It’s not only intrusive, but it can also make viewers feel like their feed has stopped refreshing as new content hides behind this face. We call this “The Face Zoom.”
