ScreenToss integrates with Imgur, an online image sharing service.
Imgur only supports image uploads.
By default all uploads are anonymous. To link an Imgur account with ScreenToss, go to Preferences ▸ General, make sure Imgur is the selected service, and click Link.
If you’re using the service anonymously and need to delete an image you upload:
Open Console (located in the Utilities subfolder of your Applications folder—you can also find and launch Console from Launchpad or Spotlight by searching for “Console”).
Filter all messages for “Imgur deletion link”.
Copy the link, paste it into your web browser’s location bar, and hit enter to visit the web page.
Confirm the deletion of the image once the web page has loaded.
