If the article you are about to replace (either by dragging a new layout from a library, or by pressing F6 to use favorite shapes), contains more linked images, but only one of those is actually paginated, since the version 1.5, Fred4 will "remember" the image that was paginated, and won't prompt you to select another image.

This makes smoother the replacement of the article layout, especially when using F6, as you cycle through all favorite shapes very quickly.

Of course, there may be situations where you don't want such behavior: you would want to select another image, among images linked to the article.

In that case, on the Images menu, click Forget Image (in lib shape selection), and on the next shape replacement, Fred4 will prompt you to select an image.
