Inserting an image into a cell, not working

Hi,

I'm creating a document in the new ePub template.

I've created a table, and inside one of the cells I've placed a small image, to which I've added a hyperlink to a website.

I'm having two issues:

1) iBooks Author automatically seems to assign that image to be the background image of the cell - instead of just part of its content. I'd rather not have this happen...

2) When previewing the book (both on iPad and on iBooks on the Mac), that particular cell simply doesn't appear, and instead I get a big X with a question mark in its place.

Help please?

Thanks
