EPUBCheck RSC-009 is a warning message: “A non-SVG image resource should not be defined with a fragment identifier.” A reference to a raster image (JPEG, PNG, GIF, WebP) includes a fragment identifier (#…), which only makes sense for SVG images.

- Official message (EPUBCheck 5.4.0): A non-SVG image resource should not be defined with a fragment identifier.
- Default severity: Warning

## Typical causes

- A URL such as images/map.png#region copied from a web page or an image map.

## How to fix it

- Remove the #fragment from the reference to the image.
