Need a better image verification during registration system.

[Viks]

Hi guys,
I was wondering .. the basic stock image verifcation system in vbulletin is okay but a lot of users complain that they cannot read the alpha-numeric characters properly and I do agree to some extent.

Is there a BETTER addon modification that can replace the exisiting image verification? (for Vb 3.5)

thanks... will appareciate yours reponses.

any suggestions?
