385853 php email text to JPG function

Hi, we need 2 basic functions to write emails on website protecting it from seach bots indexing. 1. We need a php function to create a jpg file from text. function TxtToJpg($emailStr,$filepath) If there is a temporary crating JPG file option, it can be accepted. 2. When we put this jpg email address inside the webpage, we dont want to write <a href="mailto:xxx at [login to view URL]">. The address should be encrypted by a php function, and i think we will call a javascript function like; <on click:"OpenEmailLink(<?=EncryptEmail("xxx at [login to view URL]");?>);" (if there is another solution to protect the email link, please explain it, it would be accepted) txs.
