I have my email address open on most websites I've designed and programmed for decades now, and I don't receive more spam at these address than on at those addresses which aren't public. Spammer harvest for years now using many channels: buying addresses, hacking databases, using viruses stealing complete address books from people.

Using images as anti-spam measure really gives you a lot more problems than benefits (except you'd use random single-usage addresses).

Don't obfuscate, but fix your spam filters or switch your email provider. What helps a lot is server-side moving of detected spam emails to your junk folder and looking through this folder from time to time.
