Use the 'Change image size settings' dropdown list on the Open House Flyers > Preview screen by clicking the 'Settings' button to adjust the size of certain subject property images that appear on the open house flyer document.
After changing the dropdown value and clicking the 'Apply' button your changes will be reflected on the Open House Flyer.
The default settings is: Zoom
Center - The image is displayed in the center of the image container. If the image is larger than the image container, the outside edges are clipped.
Normal - The image is placed in the upper-left corner of the image container. The image is clipped if it is larger than the image container which contains it.
Squeeze - If the image container's dimensions exceed that of the image it contains, the image is centered and shown full-size. Otherwise, the image is resized to fit into the image container's dimensions.
Zoom - The image is sized proportionally (without clipping), so that it's best fitted to the image container. If the height and width ratio of the image container is the same as the image's ratio it will be resized to exactly fit into the image container. Otherwise the closest fitting side (height or width) of the image will be sized to the container and the other side (height or width) of the image sized proportionally (leaving empty space).
