SVG

Scalable Vector Graphics (SVG) is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation. wikipedia

Federated Wiki is able to display SVG files in the image plugin in the normal way. The resulting images take up far less disk space than their raster (jpeg or png) counterparts.

SVG images and their behaviors are defined in XML text files. This means that they can be searched, indexed, scripted, and compressed. As XML files, SVG images can be created and edited with any text editor, but are more often created with drawing software.

SVG images can contain hyperlinks to other documents, using XLink. URLs of SVG images can specify geometrical transforms in the fragment section - www.w3.org

All major modern web browsers‚ including Mozilla Firefox, Internet Explorer, Google Chrome, Opera, and Safari‚ have at least some degree of SVG rendering support.

This is exactly the same SVG file but scaled to 400x400

Because of the vector nature of SVG, images that are scaled take the same amount of space as those that are thumbnail size. Consequently images may as well be scaled to the full size of the Federated Wiki image viewer.

Here is a nice article on Scaling SVG Images.
