A Collection of E-mail protection types

*****************************
This snippet has been tested with
Etomite 0.6.1.4

Using IE 7.0 and FireFox 2.0.0.12
IT works on IIS 6.x
this also works on Apache (Thanks Chris D.)
**********

Last minute Note:
TXTLINK does work, But it shows the full HTML code in the browser
like: <a href="mailto:email@address.com">email@address.com</a>
the browser doesn't render it.

So you can use it to explain how a mailto: link works

*****************************
Changes made in version 1.6 FINAL:
Minor code change/bug fix:
The text version added 2 spaces behind the AT, corrected to 1 space.

Special thanks to:

Ralph A. Dahlgren for $savePath initial idea & code to check if image exist to speed up the process.
Chris D. for tips how to create folders.

*************************

Usage:

[[Email-protect?email=email@address.com&type=txt]] (Default)
creates: &# 101;&# 109;&# 97;&# 105;&# 108;&# 64;&# 97;&# 100;&# 100;&# 114;&# 101; etc.. (spaces are added in this example)
that is rendered in the browser to look like email@address.com ( this is the default )

that is rendered in the browser to look like email@address.com ( this is the default )

[[Email-protect?email=email@address.com&type=txtlink]]
Creates: <a href="mailto:email@address.com">email@address.com</a> visible in the browser as HTML code

[[Email-protect?email=email@address.com&type=img&size=#]]

Creates a picture with the address
only this option uses the size and savePath parameters
Size defaults to 4
Folder where images are written($SavePath) defaults to "assets/images/email-protected/"
If this folder doesn't exist, it will be created with full read/write rights.
Images in this folder will be deleted when they are 86400 seconds or older (24Hrs.)

Size is from 1 (very small) to 4 (normal size)
use size 5 to make it bold (at size 4 size)
Sizes 6 or higher will default to size 5

[[Email-protect?email=email@address.com&type=dot]]
Creates:   email AT address DOT com

[[Email-protect?email=email@address.com&type=java]]
creates a click able link with Java script

[[Email-protect?email=email@address.com&type=none]]
Use no protection at all (obviously not the best to use )
