Safari Tips and Tricks: Dragging in Files
Safari, like many Mac applications, supports dragging in files from the Finder or other applications such as iPhoto. If you just drag a file into a regular browser window, however, all it will do is display the file in a Safari window. The useful part comes when a website is asking for you to upload a file. Instead of clicking ‘Choose File’, you can drag the file you want to use and drop it directly on the button.
A small green plus sign will appear next to your cursor, and the file is selected, no matter how deeply nested it is on your hard drive. This is a small thing, but it can save a lot of time if you have a file open in the Finder already before you upload it to a website.
