How to upload a Word Document to a Construct Tutorial?

I can't seem to get it to upload. I can browse the directory, select the word document in which my tutorial is written out in with images, but when I click to Open/upload the doc it doesn't take. I can copy and paste all the text, but not the images. I'd like to do it all in one swoop & then edit from there. Is there a different approach or can't tutorials accept word docs?

Thanks

Yeah, the C2 tutorials section is seriously broken. You can't upload certain files, can't insert code, can't leave comments, can't switch language... And Scirra team doesn't seem to care.
