How do I remove an attachment?

[Helen M]

I've posted the wrong picture in a post (pattern for sale).

I've tried to remove it by modifying but to no avail. Can someone remove them for me please?

I've done it for you, but if you click on the green 'Actions' button (top right of post), then choose 'modify' and click on the attachments facility at the bottom you will see the attachments with tick boxes alongside them.  Un-tick the boxes and save the post.

Ah thank you Acorn! I hadn't unticked the boxes..........
