Losing image alignment when converting to PDF

[junkman]

Hi all, below is a screen shot showing, on the left, the front page of a report as it looks while I work on it, and on the right, how the same page comes out in print preview and after conversion to pdf. The whole document comes out like this - I have a lot of images placed in table cells and they all come out stacked in the top left corner of the page.

The wrapping for the images is set to in line with text. Anything else I should look at? Any help much appreciated
