I was recently wondering how to do this as well, and just thought of a solution.
You can use an Android cloud storage app with an "Auto Upload" feature (e.g. Dropbox), and also install the app on your computer so the pictures sync from your phone to computer. Then you can use Evernote's "Import Folders" tool to monitor new files in this folder, and choose "Source: Delete" so your cloud storage account doesn't get filled up, and the pictures are still saved in Evernote.
I also found this service Filterize that can assign the photo dates to the Evernote "note creation date", so your library of older photos keeps its order when put into Evernote. It works by searching Evernote note titles for dates (the note title will be the same as the photo filename), so if your filenames have dates in them, then you can adjust it to read and apply those dates.
