CorelDRAW Graphics Suite X4 :: How To Link JPEG Images

I use corel draw to assemble jpeg images I have exported from another application into a presentation which I then publish to pdf.

My problem is that whenever I update the images I have to re-insert and position/scale each one again in the corel presentation.

I've been trying to work out how to do this with linked files or OLE objects, but without success.

Is there a way to link or embed jpegs so that if I update the original jpeg it will update in corel draw?

I've tried to follow corel help but it doesn't work. Inserting an OLE just puts a box with the jpeg filename on the page, and it prints as just a box with a filename as well.
