png files visible with ImageMagick but not on web browser.

Hello,  

I am using ROOT version 4.04/02f to produce png files in batch mode. The files are produced and can be viewed perfectly with the ImageMagick component display. When I try to view the files using a web browser or on Windows I ge something like:  

The image
"blah.png"

cannot be displayed, because it contains errors.  

However I can use ImageMagick to reproduce the format. I.e. save as
"blah.png" and overwrite the old version, and then the file can be
viewed without any problems.  

Does anybody know anything about this problem and how fully usable png files may be produced directly from ROOT?  

Many Thanks,
