I have a script that requires ImageMagick and after a lot of digging, found this to work as the path setting:
/usr/X11R6/bin/convert
I can't remember where I found the reference, but that works on the server where my site is located.
Dick and Terri,
I'm glad that you and yours are safe. As a former Houston resident (1978 - 1981), I know all too well how low and subject to flooding that so much of the area is.
Please stay safe, and I hope that your power is restored soon.
