<a href="http://www.add-art.org/" rel="nofollow ugc">Add-Art</a> is a <a href="http://www.mozilla.com/en-US/firefox/" rel="nofollow ugc">Firefox</a> plug-in that replaces website advertising. Created with support from <a href="http://eyebeam.org/" rel="nofollow ugc">Eyebeam</a> and <a href="http://rhizome.org/" rel="nofollow ugc">Rhizome</a>, Add-Art releases new art shows every two weeks and strives to feature contemporary artists and curators.
The plugin works alongside <a href="http://adblockplus.org/" rel="nofollow ugc">AdBlock Plus</a>, which blocks online ads, and simply replaces that blank space with art images. AdBlock Plus is the most popular of the thousands of available add-ons for Firefox with 18 million total downloads (as of May 2008) and over 250,000 downloads per week.
For many, replacing ads with blank space would be enough. AddArt attempts to do something more interesting than just blocking ads – it turns your browser into an art gallery. Every time you visit the New York Times online or check the weather you’ll also see a spattering of images by a young contemporary artist.
The project is supported by <a href="http://add-art.org/" rel="nofollow ugc">add-art.org</a> which provides information on the current artists and curator along with a schedule of past and upcoming AddArt shows. Each 2 weeks will include 5-8 artists selected by emerging and established curators.
Images need to be cropped to standard banner sizes or can be custom made for the project. One group of images is shown per page. The curatorial duty is passed among curators through recommendations, word of mouth, and solicitations to the Add-Art site.
With the overwhelming popularity of adblockers, if Add-Art were to attract 5% of existing users, the numbers would be in the hundreds of thousands. Add-Art can bring contemporary art to the desktops of all types of people at home and in their workplace – all over the world.
Would you like to see art instead of ads as you browse sites online? Go to <a href="http://add-art.org/" rel="nofollow ugc">add-art.org</a> and download the plugin for your Firefox browser now.

This plugin has two modes – basic and Akismet-enhanced.
Basic mode: the plugin will serve a CAPTCHA to all commenters that aren’t logged in and don’t have a previously approved comment. Repeat commenters will never see a CAPTCHA.
Akismet-enhanced mode (recommended): the plugin will serve a CAPTCHA only if Akismet identifies a comment as spam (much less frequently than the basic mode). Just install an activate <a href="https://wordpress.org/extend/plugins/akismet/" rel="ugc">Akismet</a> to enable this mode.
Note that a CAPTCHA will only appear after a comment is submitted. When a commenter is served a CAPTCHA:
<ul>
<li>If they fail, then the comment will be automatically discarded or trashed (and won’t clutter up your spam queue).</li>
<li>If they pass, it will be allowed into the spam queue (or approved, if you so choose). This means that any false positives from Akismet will be easily identified without you having to trawl through all the spam comments manually.</li>
</ul>
Most genuine commenters will be able to comment on your site hassle-free, without ever seeing a CAPTCHA.
The default CAPTCHA is a simple text-based test. There is also the option to use <a href="http://www.google.com/recaptcha" rel="nofollow ugc">reCAPTCHA</a> if you want something more robust (free API key required). You can also style the CAPTCHA page to fit with your own WordPress theme.
If you come across any bugs or have suggestions, please use the plugin support forum or <a href="http://rayofsolaris.net/contact/" rel="nofollow ugc">email me</a>. I can’t fix it if I don’t know it’s broken! Please check the <a href="https://wordpress.org/extend/plugins/wp-conditional-captcha/faq/" rel="ugc">FAQs</a> for common issues.
