Reimagine was designed and built as a mobile application only.
If you wish to view the scanned and improved photos on your computer, you can log in to MyHeritage.com, click on the ‘Photos’ tab and work with your photos there.
NOTE:
If you have a Reimagine subscription, you can use all the Photo features on MyHertiage.com. Just be sure to log into MyHeritage using the same email address and password that you use to log into Reimagine.
