image_url()

renderer_base::image_url ( $imagename, $component = 'moodle' )

The imagename is for historical reasons a relative path name, it may be changed later for core images. It is recommended to not use subdirectories in plugin and theme pix directories.

There are three types of images: 1/ theme images - stored in theme/mytheme/pix/, use component 'theme' 2/ core images - stored in /pix/, overridden via theme/mytheme/pix_core/ 3/ plugin images - stored in mod/mymodule/pix, overridden via theme/mytheme/pix_plugins/mod/mymodule/, example: image_url('comment', 'mod_glossary')
