flickpress is a tool to find Flickr photos and insert them into your posts, plus a widget to display recent Flickr photos.
The widget just packages the template function in convenient widget form. To use it, activate it through the 'Plugins' menu in WordPress and add it to your sidebar through the 'Widgets' menu. It requires some things in the main plugin, so you'll need to have both activated.
Just like with the template function, you may specify a class for the images, and text (such as HTML tags) to display before and after each image. Some tips:
</p>after or just a
There are a couple of different ways to enable lightbox support for images inserted with flickpress.
Another fairly easy method is to turn on the Custom lightbox option in the settings and install a lightbox plugin that automatically recognizes lightboxable image links. The Lightbox Plus plugin has worked for me with this method, and has lots of customization options.
There is a simple template function available for use in your sidebar or other spots you'd like to include a few recent flickr photos. The function, its options, and the defaults are:
if (function_exists('flickpress_photos')) flickpress_photos($email,$numphotos=3,$before='',$after='<br />',$fpclass='centered');
This plugin is really just a wrapper for Dan Coulter's excellent phpFlickr library ( http://phpflickr.com/ ). Using more than one plugin based on the library can cause conflicts, so I renamed the class in the library included with flickpress. I also edited (maybe broke!) the database cache code, so if you're considering creating a plugin based on flickpress I highly recommend getting the latest official version of phpFlickr instead of using this modified version.
