The first thing you'll want to do after signing in to Photoshop Express is to upload some of your photos. This is a simple matter of browsing your computer drive and selecting the photos you wish to upload. You can upload several photos in a batch; they do not need to be uploaded one at a time. If you wish, you can create an album for the newly uploaded photos, add them to an existing album, or just import them to the library.
Photoshop Express gives a detailed report of the upload progress and displays a message when the upload is complete.
A drag and drop upload tool would be nice, but is currently not available.
