How do I retrieve the photos on iPhoto?
If you exported or dragged them out of iPhoto, they can be opened in Preview, imported into Photos, or otherwise treated as ordinary files.
If you put an entire iPhoto library there, launch Photos with the Option key held down, click on Other Library, and choose it.

Thanks Niel, but the iPhoto app doesn't open at all. It just looks like that:
You don’t need to open iPhoto to do any of those. It’s not the same as Photos.

Niel's comments about using the option key before launching Photos will prompt you for the library location (your USB stick). Your version of iPhoto is out of date per that icon image you posted.
OS X does not bundle iPhoto, it was available via the App Store. If you had updated to iPhoto v9.6.1 for Yosemite compatibility, and an iPhoto library is present, the installation of OS X 10.10.3 or later will install the new Photos application, without removing your iPhoto application or its library.
The first time you launch the Photos application, it will automatically locate the iPhoto library, and build a new Photos library. Subsequent additions to the iPhoto library are not automatically updated in the Photos library.
Not the topic of this discussion, but I have to say that (IMO) Photos is two steps backwards from iPhoto.
The updated version on my mac does not have iPhoto. How do I view the photos which I'd saved on iPhoto on a USB?
