Similar to OpenAudioEditor, except that it is for stills. In additional to the usual formats like jpg, png, bmp, etc. it will also open Camera Raw images from the timeline as well as PSD files. Like OpenAudioEditor, the edited image is not added back to the timeline until processing is completed. Also, copies of the script may be made so that multiple editors can be called.
When the script first runs, the following window is shown. A left-click on the folder icon opens the file dialog from which the filepath to the photo editor must be selected.
