S3 force download of a file

In using S3, both download methods appear to let the browser control whether to view them or download them. Is there a way to force a download?

For example, if you use the download method to open a jpeg file, the image loads in the browser and there is no obvious way to download it (outside of right-click, save image as). If you download an Excel file, it immediately goes to your download folder.

In other Skuid solutions where I use Google Drive, I have full control over view and download by changing the URL. Is there a way to do something similar with S3?
