Hi Jonathan,
If by 'resize' you mean increasing the the resolution of the photo, yes you would need another app for that to blow up the photo. You may use the search function to look for apps in the Windows Store or Bing. As a work around though what we suggest - if it's to a resolution that still fit a 1080p (wide) screen- is to zoom in on the on the original image then use the snipping tool that is a built-in app to windows.
Should there be anything else do let us know.
