The originals I uploaded are much higher quality. <o:p></o:p></p><p style='margin-left:36.0pt'> <o:p></o:p></p><p style='margin-left:36.0pt'><img border=0 width=630 height=418 id="_x0000_i1026" src="cid:image001.png@01CCD432.955CC500"><o:p></o:p></p><p style='margin-left:36.0pt'> <o:p></o:p></p><p style='margin-left:36.0pt'> <o:p></o:p></p><p style='margin-left:36.0pt'>However no such degradation is apparent with PNG files as shown below: (as before the original is at the bottom and the Xerte rendered version at the top).

For the short term I can use PNGs rather than JPGs but it introduces an extra work layer and It doesn’t help the dozens of LOs that used to look crisp and now look fuzzy.
