Error Producing Security Image

Hello,

I've installed Dolphin 7.0 and have all the permissions set properly, Use GD library for image processing has been checked, but getting an "Error Producing Security Image" in the captcha field of the Join page.  Have tried searching the forums but can't seem to find a solution to resolve this issue. Does someone know how to get the captcha image to show?
