After that, upload the image file into machform folder and edit your 'captcha.php' file inside machform folder. You'll see these code inside that file :</p> <pre><code>$fonts = array(&#39;lib/php-captcha/VeraSeBd.ttf&#39;,&#39;lib/php-captcha/VeraBd.ttf&#39;); $captcha = new PhpCaptcha($fonts, 200, 60); $captcha-&gt;Create();</code></pre> <p>then change it to </p> <pre><code>$fonts = array(&#39;lib/php-captcha/VeraSeBd.ttf&#39;,&#39;lib/php-captcha/VeraBd.ttf&#39;); $captcha = new PhpCaptcha($fonts, 200, 60); $captcha-&gt;SetBackgroundImages(&#39;mycolor.jpg&#39;); $captcha-&gt;Create();</code></pre> <p>That would change capcha background with "mycolor.jpg" </p> https://www.machform.com/forums/topic/captcha-transparent#post-11409 Mon, 14 Feb 2011 06:44:41 +0000 djones 11409@https://www.machform.com/forums/ <p>Possible to make the captcha background color transparent? This way I could color forms different colors without having the white captcha block showing </p>
