I still have the problem related to LyX unable to render an image on

"Error converting to loadable form".


I have installed, as suggested, ImageMagick. Added the
$ImageMagick/bin to $PATH, added it to LyX path, tried "convert" from
a shell (outside its directory) and it is working, but LyX still keeps
telling me that error.

The debbuging option shows the following text:

       The file contains png format data.
       No conversion needed (from == to)!

Some new suggestions on this problem???

Do you have Ghostscript installed? ImageMagick uses GS to convert PS,EPS and PDF files.
