the date the user joined Galaxy Zoo, the number of galaxy classifications
and the latest classified galaxy.
The second widget, ‘Galaxy Zoo Favorites’, displays thumbnail images of
galaxies the user selected as his/er favorites (using the Galaxy Zoo’s My
Galaxies page – http://galaxyzoo.org/my_galaxies)
Both widget are completely customizable via the widget’s control panel and
style-able via a separate css file(s).

time of your blog (if AJAX is disabled, the Galaxy Zoo data will be loaded before

- How do I get the plugin work with my Galaxy Zoo account
As of the moment, only selected beta testers from Galaxy Zoo forums were
given API keys required by the plugin to access Galaxy Zoo account data. If
you would like to stay informed and be notified when the plugin becomes
available to the general public, sign-up at Galaxy Zoo Forums
- How do I change the background on the AJAX preloader
The preloader can be changed via the plugin’s CSS: On you WordPress Dashboard
select “Plugins” then “Editor”, then select “Galaxy Zoo” in the
“Select plugin to edit”. Finally, select the “galaxy-zoo/css/galaxy-zoo.css”.
Now you can edit the plugins global CSS (change made here will be made to both
widgets)… Look for the ‘.widget-galaxy-zoo-loader’ class declaration and
change the value inside the ‘url’ brackets, e.g. from url(../img/loader-dark.gif)
This plugin comes with 2 preloaders, one dark with background color
- 222222, and one white, with background color #FFFFFF (loader-white.gif).
If you would like to have a preloader with a different background color
use the online preloader generator at http://www.ajaxload.info/
Select “Big Roller” as the “Indicator type”, the background color you wish
to have and #FF5D05 for the “Foreground color” (although you may change
this value as well if you wish). Finally, click on “Download it!”.
Once you have the new preloader image saved on your machine, you will need to
upload it to the plugin directory at /wp-content/plugins/galaxy-zoo/img
