The parsing is done without any echo, therefor should bypass the bot. Sorry for my double-post! small update:

The basic principal of this is: An image with code is created, and parsed into javacode. The Javacode needs to recognize the image. But, here's the fun part: A bot doesn't pre-process the javascript, as where a real browser does, usually. Therefor, it is partly working. The idea is gonna be the next spamfight I hope. Working on it, I might let ya all know how ;) the more effective solution nowadays is to use a “random code”

We might suggest that instead of placing the input field at the end of the form, it may be best to place it at the beginning, just before the first true input field. That way, when the visitor selects the first input field, they will have no "double-tabbing" while they proceed through the form, and they won't have to double-tab when moving from the input fields to the submission button. Again, thanks for the feedback! That’s an excellent point, thanks for bringing it up.

If you are going to use this technique, you probably want to put this field at the very end of the form. Given the input field is not actually hidden, but is moved out of view, it is still a rendered object and would be part of the tab sequence as you move through your form. May not be a big deal to most, but certainly could be confusing or even troublesome to the well intentioned site visitor with special browser settings (such as the visually impaired).
