Verification Image

[Barkster]

I've done image verification using a predefined background image before
and never really liked it but I found one here that seems to
dynamically create the whole image instead of using a static background
image. Can anyone tell me how to do one like this? Thanks

Sorry I misread your question... Yeah the background is different each
time and its always arcs of different size/colours + position, they
could be using imagearc with some randomised arguments + overlaying the
text on top.
