When clicking an image file (like JPEG) in Chrome, you can have Chrome open immediately instead of first Saving (or downloading)
In order to set this up, click on a hyperlink in eSPACE for an image file (like JPEG) and then you will see an icon appear in the lower left corner (see below).
Click the little up arrow to see a menu of options.
Now choose Always open files of this type.
