Q: viewing my macbook photos from a pc

Howdy vincentyong,

You don't say if your Mac and PC are both connected to the Internet.  That is a good way to share your pictures from the Mac.

For example:

iCloud Photo Sharing FAQ - Apple Support

With iCloud Photo Sharing, you can share photos and videos with just the people you choose, and you can let them add their own photos, videos, and comments. Friends and family can subscribe to your shared albums to view them on all of their devices, leave comments, and get notified automatically when you add new photos and videos.

 

What do I need to use iCloud Photo Sharing?

 

To use iCloud Photo Sharing, you need an iCloud account (Apple ID), compatible devices, and up-to-date software:

 

• iPhone, iPad, or iPod touch using iOS 7 or later
• Mac using OS X Mavericks v10.9 or later and either iPhoto 9.5 or Aperture 3.5
• Apple TV with Apple TV software 6.0 or later
• PC using Windows 7 or later and iCloud for Windows 4.0 (or iCloud Control Panel 3.1 or later)

If your Mac has Yosemite, you could also use iCloud Drive.

With iCloud Drive, you can safely store all your presentations, spreadsheets, PDFs, images, and any other kind of document in iCloud. Documents you store in iCloud Drive will be kept up to date across all of your devices, and you can access them from your iPhone, iPad, iPod touch, Mac, or PC.
