Error for convert command in command line

Question

I have a bash shell script as below.

#!/bin/bash  SIZES=("512" "1024" "2048")  for i in ${!SIZES[*]} do     SIZE=${SIZES[$i]}     echo $SIZE      # first, resize original image     convert -resize $SIZE"x"$SIZE! chernarus2048.jpg chernarus$SIZE"x"$SIZE.jpg     mkdir tiles$SIZE     # slice resized image into 256x256 tiles     convert -crop 256x256 chernarus$SIZE"x"$SIZE.jpg tiles$SIZE/tile%04d.jpg     rm chernarus$SIZE"x"$SIZE.jpg done 

But when I run this in command line using the following command

sh generate_tiles.sh chernarus2048.jpg 

I'm getting an error convert: command not found

I'm using OS X Yosemite 10.10.2.The image is kept in the same folder where the shell script is placed. Please help me out.
