Smallish hack here, basically it emulates Yahoo's, among other's, system of generating an image with a random series of characters that a user must enter correctly into a text box to register. The screenshots will illustrate this well:
Installation Instructions
----------------
See install.txt in the attachment
Minimods
---------------- Text-only version for people without access to the GD library
The font may be customized by taking a font desired, in TrueType format, and uploading it in place of the font.ttf included. the gd image library IS required to use this hack.
Is there a way to use something other than the gd library to display the images (since alot of hosts don't have it installed)? If the text only version can be got around that easy, there must be another way.
Yea, I already made that into my hack, you have 3 choices on how the output images are, two are for gd, one is for non gd, the gd options are:
Creating one verification image from multiple others like a.jpg 4.jpg anf so on
Creating one image with the text written in the center of it
and the non gd:
Displaying multiple images for each char that bots and users cant trace back to the actual image and get the value of it.

Code:
<tr>
<td bgcolor="{tableheadbgcolor}" colspan="2"><normalfont color="{tableheadtextcolor}"><b>Image Verification</b></normalfont></td>
</tr>
<!-- *** -->
<tr>
<td bgcolor="{firstaltcolor}"><normalfont><b>Image Verification</b></normalfont><br>
<smallfont>Please enter the numbers and text that you see on the image. This is to help prevent automated registration.</smallfont><br>
<img src="imagegen.php?hash=$verifydata[hash]"></td>
<td bgcolor="{secondaltcolor}"><normalfont>
<input type="text" class="bginput" name="verification_value" size="25" maxlength="100">
<input type="hidden" name="verification_hash" value="$verifydata[hash]">
</normalfont></td>
</tr>
Thats the template I use for my hack to display the image in the register section, verification hash isnt the actual value of the image, its the hash of the current register verification session, this makes it impossible for ats to get the actual value of the image.
You should make your letters to change position, in different angles and also place some grids over... I know it can be done, FireFly showed me something cool like that...
If you get it to do this, OCR software cannot scan the letters and insert them automatically.
