> what "weirdness" were you thinking of in the image placement?
Maybe I was being a little obtuse, and 'weirdness' wasn't the right phrase :)
When placing images in Layout mode you have a couple of options.
The 'easy' one is to add the images directly (either via drag-and-drop, via the Media tab in the toolbar, or the Insert -> Choose... menu option). These will typically create a floating image that you're free to drag around and place anywhere on the page as you like, and text will flow around this (based on your formatting choices). The image position doesn't change as the text on the page changes.
On the other hand, it's possible to embed an image inside a text box. In this mode the image flows with the text - add lines of text above the image and the image shifts down the page (and vice versa).
In this mode you can just type a line of text above (or below) the image, and they'll naturally stay together (page breaks notwithstanding).
If you use the separate image and text boxes they are independent and can be moved anywhere on the page. The means it's possible (easy?) to move an image and lose the visual connection to its caption. In this case, you can select the text box and the image and use the Arrange -> Group menu to group the items together. This enables you to treat them as a single object, so moving the image will inherently move the text box with it.
Maybe none of that it 'weird', but it does mean the mechanics are a little different depending on how you've placed your images and text.
