Just log in to your Dropbox account in any browser, right-click on your photo, and select Delete. If you're not sure which one you need to delete, you can view your photos in the same browser.
So, 3 steps in total:
- Go to dropbox.com.
- Log in.
- Delete.
Installing the Dropbox client is certainly not easier, because the process goes something like this:
- Go to dropbox.com.
- Download the client.
- Install the client.
- Log in.
- Pick the synchronisation folder.
- Wait whilst Dropbox downloads the entire contents of your cloud storage to that folder.
- Remove the file from the synchronisation folder.
- Synchronise Dropbox - whereby it deletes the photo on your cloud storage.
8 steps in total. Actually, the whole idea of downloading a file in order to delete it sounds completely bonkers to me.
