Q: how do i send 25 photos on my mac

If 3 MP versions are good enough, send them via iCloud Photo Stream. If your email provider will cooperate, you can send full-resolution images via email, though you might have to send them in smaller batches. Just drag them into an email and select the Actual Size option when you click Send. Otherwise, if email doesn't work for that many large pictures, set up a Dropbox account and drag them into a folder online. If you don't want them on the Internet at all, buy a USB drive and mail them.

You can also put all 25 images in a folder, compress them, then e-mail the ZIP file to whomever you want to receive the pictures.
