Mr. Thyssen worked out the solution in offlist emails with me.
I needed the -flatten option for the png background to be white.

Here is a copy of the solution:

convert  -density 288  lightcurve.eps  -resize 25%  -flatten lightcurve.png 

Thanks, I will post this to the original thread for the benefit of others.
