Type
  • identify -list format
The JPEG format should be listed and have a mode of rw- (meaning it can read it and write it). If not, try running the configure script again and ensure it recognizes the JPEG delegate library on your system. Next, clean the distribution (make clean) then rebuild and reinstall.

You can find the JPEG library with the Google search engine. Once its installed, rerun the ImageMagick configure script. Look at the last 30 lines of output from the script and ensure it says the JPEG delegate library was found. If not, fix whatever complaint you find related to JPEG in the config.log file. Once the configure script validates the JPEG library, build and install ImageMagick and you will be able to read/write JPEG images.

I installed IM from a binary Mac OS X distro (here). I'm receiving this error when trying to convert JPEG files. Any advice, short of learning how to build from source?
