Email PNG
Want to display your email, but scared it'll get picked up by spambots?
Then you need the imaginatively titled Email PNG!
Here's how it works, in your html source, use this simple code:
<img src="email.php?text=(base64_encoded email address">
email.php will generate a png fo the right size, with an invisible background.
You can even customise the colour, something like this:
<img src="email.php?r=100&g=5&b=100&text=(base64_encoded email address">
where 'r', 'g' and 'b' are the amounts (0 to 255) of red, green and blue to use.

Says: use the hash calculator in the online tools section to create your base64_encoded string, or use PHPs base64_encode function.
and yes, it's not going to stop a spambot if it's been customised to recognise and decode base64'ed strings, but I really don't think spammers are that clever.

Says: no, there's no password, base64 is a bit like rot13 - just a method for encoding (rather than encrypting, which would require a password)

Says: Nice script! , one thing that i added to it was a bit of "protection" with the following code :
$use_only_in = "www.puremango.co.uk";
if (!strstr( $_SERVER['HTTP_REFERER'] , $use_only_in )) {
exit;
}
at the start of the script, this prevents people from other sites from using the script unless the referer is your own site.
The downside to this is that you wont be able to call email.php directly,without using , but that would be such a big deal.

just put the img tag whereever you want an email address to be displayed on your website.
Add your comments:* denotes a required field.
Your email address will be converted to an image to prevent spambots picking it up.
