I created a captcha image ("image.php") and am trying to add it at the end of my registration form to work together with the rest of the form. (where it says "CAPTCHA IMAGE HERE"). This is what my script looks like from the captcha down:
<tr>
<td><div align="right"><font face="Tahoma, Geneva, sans-serif" color="333333">State</font></div></td>
<td><select name="state">
<option value="<?php echo "$state"; ?>"><?php echo "$state"; ?></option>
<option value="Alabama">Alabama</option>
<option value="Alaska">Alaska</option>
</select></td>
</tr>
<tr>
<td><div align="right"><font face="Tahoma, Geneva, sans-serif" color="333333">City</font></div></td>
<td>
<input name="city" type="text" value="<?php echo "$city"; ?>" />
</td>
</tr>
<tr>
<td><div align="right"><font face="Tahoma, Geneva, sans-serif" color="333333">Email</font></div></td>
<td><input name="email" type="text" value="<?php echo "$email"; ?>" /></td>
</tr>
<tr>
<td><div align="right"><font face="Tahoma, Geneva, sans-serif" color="333333">Password</font></div></td>
<td><input name="password" type="password" value="<?php echo "$password"; ?>" />
<font size="-2" color="#006600">(letters & numbers only)</font></td>
</tr>
<tr>
