[magick-users] identity and convert fail with 'Improper image header'

[Ignac Vucko]

Thanks for the idea zentara,

But, unfortunately, I have 200K images to convert, about 2K of which 
exhibit this phenomena...
I was hoping there was a "force" flag that would allow imagemagick to 
treat a file as .ico and ignore
the fact that the header is not "perfect".

Is there another command line linux tool I can use to convert or correct 
the images?
