- when more than one picture is anchored to the same paragraph, you only need to select the paragraph, then copy it. The pictures will follow when you paste the paragraph; and
- when you click on an image that is Wrapped inside of a paragraph, if ▸ option in the image toolbar is selected, the anchor of the image is displayed at the beginning of the paragraph. It is therefore necessary to copy from the beginning of the paragraph to make sure the anchor will be copied, to the next paragraph mark.
