Providing basic functionality, Image Loaders allow you to load an image to a texture which Compiz can use for rendering. Each image loader allows loading certain image types into textures, like JPEG, PNG and SVG. The Text plugin is a library plugin that provides a font to applications to draw text, such as window titles, on screen.

JPEG image filenames usually end in the extension .jpg or .jpeg. It is important to note that your success in loading images with this plugin may be varied, and may result in white images or textures when loaded. JPEG images also do not support an alpha channel, making them useless for certain plugins. They are also not scalable, and the image quality may drop if the image is scaled up.
Only use JPEG images if they came from a source like a digital camera or the web. If you are looking to create images for use with Compiz, use PNG.
Compression Quality Refers to how much the image compressed when used as a texture. A lower quality will result in a lower quality image, but less of a memory footprint.

PNG images usually end in the extension .png. You will generally have more success loading PNG images, and PNG images also support an alpha channel, allowing compiz to draw real transparency where the image is transparent. PNG images however are large in size, and are not scalable - causing distortion when they are scaled up.
Use PNG images wherever possible as they have a much sharper quality.
SVG

SVG images consist of a mathematical forumla (XML) to draw an image. They do not contain bitmap data. SVG images typically have the extension .svg. SVG images also support an alpha channel allowing for Compiz to render true transparency. SVG images can also be scaled up, but Compiz currently imports the default size to a texture.
