Browse and select the image containing a pictorial representation of some aphpa-numeric characters that the user should be able to read and enter as a means of spam protection.

The image should be relatively small and contain about 4 characters. If you are creating your own spamcode images avoid letters and numbers that look alike - such as 0 and o or 4 and 9 or i and l(L) and 1. Use a mix of upper and lower case letters and numbers and several different typefaces.
