It’s more than one time when I asked my friends to send me some photos of a trip or event, and I got an email with more than 20 photo attachments files (>.<). Actually there is a way to send many photos in only ONE compressed zipped file. Hope this will be helpful to you if you don’t know.
1. Copy the photos you want send in one folder.
2. Move your mouse on that folder’s icon, and then right click the right button.
3. Select "Send to…" –> "Compressed Zipped Folder"
4. It will come out a notice window, just click "Yes"
5. You can use email attachment to send this file, but here is a site you might want to check it out: "http://www.yousendit.com"
That’s all, just as easy as that! Then you will see a new zipped file comes out, that’s the file you need to send to your friends. When your friends received this file, they can open it straight forward without needing to install a third party software.
Finally post a picture that might help:
