I have four charts on one worksheet. All are the same size, all have the
same small jpg image imbedded in the chart area. I have not adjusted the
sizing of the image, the chart or the rows or columns. When viewed in normal
mode, the image looks just fine. However, when print previewed or printed
the image in some of the charts will distort to about 1/6th its height.
Whats worse, is that this is intermittent (but very common) and which
chart(s) affected is different every time I print preview or print. It also
does not matter what printer I am sending it to.

Is this a known issue and are there any fixes?

Image properties:
pasted onto Chart area
Locked aspect ration
I've had the issue under both curcumstances "Size with Chart" and "Do not
size with chart".
