I want to add a service to Safari with Automator, which performs a series of actions (e.g. cropping) on a single image from the web.
The first step should be to right click an image in Safari, similar to an action for rich text (see 'Custom Text Action' in first screengrab), but the relevant settings in Automator only seem to work across an entire webpage, rather than a single image.
What should the input settings of my service be to achieve this? 'Web content' seems like the obvious choice (see second screengrab) but I can't see where this can be activated?
