How can I use Apple's iPhoto to upload photos? How can I export from Apple Photos?

iPhoto is a discontinued digital photograph manipulation software application developed by Apple Inc. It was included with every Macintosh personal computer from 2002 to 2015, when it was replaced with Apple's Photos application. On April 8, 2015, Apple released OS X Yosemite 10.10.3, which includes the new Photos app. iPhoto and Aperture were discontinued and removed from the Mac App Store.

iPhoto no longer functions with dotphoto.

How to upload from your iPhone to dotphoto

Export photos from Apple Photos
You can export photos so that you can import and work with them to dotphoto. You can also export a Live Photo as a still image. You can choose the size and format for the exported photos.

1. Select the item you want to export. Choose File > Export > Export [number] Photos.
2. Click the Photo Kind pop-up menu and choose the file type for the exported photos. Choose JPEG
3. Click the File Name pop-up menu and choose how to name the exported files (this step is optional).
4. You can name your exported files using the titles you’ve given them in Photos, their filenames, or a filename numbered sequentially. If you choose Sequential, you can specify text to appear before each number (for example, Birthday01, Birthday02, and so on).
5. Click the Subfolder Format pop-up menu and choose how to divide the exported files into folders. For example, if you export photos from several different moments, you can have Photos export each moment as a subfolder named after the moment. Choose None to export the photos as individual files without subfolders.
