Smilesforu,
You will find alot better support over at Photopost forums on those issues. ImageMagick by far is the best quality program.
Now your problems are real easy with Mogrify
If you are getting a 127 error (usually indicates "file not found");
- Verify the path in $mogrify_command (in your config-inc.php file) is set to the full executable. You can check the location of mogrify on Unix/Linux systems by typing which mogrify at a command line and it will return the path
If you have a Error 126 then your error is this
Your "mogrify_command" in the config-inc.php does not include the full command.
So in the first one you most likely had the path to mogrify wrong.
In your second error lets say for instance Mogrify is in
/usr/bin you had your config-inc.php file set to /usr/bin
instead of /usr/bin/mogrify
