Page break before image

Currently if there isn't enough space at the bottom of a page for an image then a page break is inserted and the image is placed on the next page. This is great and probably the expected behavior most of the time. :-)

Is there a way though from preventing this from happening ?
In certain cases I would like the image to be placed even if there isn't enough space, with the remaining part of the image either dropped, or to overflow onto the next page.

If there isn't already a way to do this could the css style `overflow: hidden/visible` maybe be extended to be able to accommodate this ?
