All the image plugins load images, but you can always map these across to height fields youself if you so wish. Height fields require extra information over what plain images provide, for instance height fields have an origin and XY intervals and only height values, while images have no spatial information like this, but can have RGBA. Mapping 1:1 isn't really possible without making some huge assumptions on the spatial and pixel mapping, but if you make these assumptions you'll never provide an accurate answer to anyones problem.
