I have a vm running ubuntu with CF 8.01 and I am testing cfimage to create a captcha and it fails on linux but not on my windows and mac boxes. The error I get is the following:

The VERDANA,ARIAL,TIMES NEW ROMAN,COURIER font name is/are not supported. The problem is that this works on windows and mac? Here is the code?

text="#arguments.text#"

width="#arguments.width#"

height="#arguments.height#"

fonts="verdana,arial,times new roman,courier" />

I checked on the CF admin, and all of the fonts are installed. So why do I get this on Linux based cf? Any ideas?
