My drawings contains some inserted reference images. I use Print to PDF function in DraftSight which is very handy cause I don't need any other 3rd party software/driver to get an output PDF.

The problem is, when I view the PDF file using Docucom, I can't see some of the images included in the drawing. The strange part is also that, when I use Adobe viewer, everything seems to be in the PDF.

Now you might suggest to just use Adobe instead of Docucom, but what I'm really wondering is why not all the images in the drawing are missing when the PDF is viewed using Docucom. Actually, out of the 10 images inserted, only 1 or 2 are missing.

Thanks in advance for your reply.
