You are only capturing one variable in your rewrite rule.
You need something like:
RewriteRule ^([A-Za-z0-9_-]+)/([A-Za-z0-9_-]+)/([A-Za-z0-9_-]+)/?$ process.php?width=$1&height=$2&third=$3 [QSA,L]
or, a bit shorter:
RewriteRule ^([\w-]+)/([\w-]+)/([\w-]+)/?$ process.php?width=$1&height=$2&third=$3 [QSA,L]
(the \w word character includes letters, digits and underscores)
I have made only the ending slash optional so this rewrite rule would only do something if there are exactly 3 variables.
