In Inkscape you put a shape on top of an image, then apply the clip and it gets clipped to the shape. That works with paths but also bitmaps.
It may seem unintuitive but you can work with raster images in Inkscape too.

Yes, but it seems like a design choice by the developers which i dont understand. It seems they just omitted a step on purpose (filled paths).

PS slips a clipping path into jpegs which as far as I know not used by other applications. I suppose because jpeg does not support an alpha channel. It is possible to use gimp and a path to isolate part of an image. Tiff + path as this in Scribus

Indeed. I have an image from a PS CD, that says its clipped (to a circular shape). But i cant unclip it.

EDIT: here it is

It opens unclipped in PS, with the clip applied in Gimp and unclippable in Inkscape.
