I just got finished fighting with this, and here is what I learned...

First!!! NetPBM and ImageMagicK are optional. They will not be used, or shown as available if 'Select the Image library to use' in newBB preferences, is set to something else.

Second, Under Windows the paths entered in the newBB preferences can not contain spaces. If NetPBM, or ImageMagicK have been installed under 'C:\Program Files\' use 'C:/progra~1/' in the path.

Which brings up the last point... Use forward slashes in the path.

I did default installs of recent netpbm and imagemagick win32 binaries. The paths that worked for me were...
C:/Progra~1/ImageMagick-6.3.7-Q16/
and...
C:/Progra~1/GnuWin32/bin/

Now, can someone knowledgeable please tell me how each, including GD2 rate for speed, memory footprint, image quality, etc.

Thanks in advance


For google sake I better go ahead and say... configure setup forum and
NetPBM not available
ImageMagicK not available

I know this has been dealt with before. Yet in other posts the answers were not immediately apparent. They were either dealing with *nix servers, or the right answer was nestled among 5 other 'Try this..' posts. Hopefully search engines will pick this up, and it'll never be an issue again.

Same problem here... anyone?
