A .zip file is simply a compressed folder that holds all of the individual photos within it. Think of it like putting the individual photos into a box which makes for easier and faster delivery (upload and download). When the buyer downloads your .zip photoset, they "open" it and can enjoy the full photos.
Creating a .zip file of your photos
1. Create a new folder on your computer and name it as you wish for the photoset (ie. myphotos12).
2. Drag or move all of the photoset photos into the new folder
3. Convert the folder into a .zip file (right click and "send to .zip" in Windows)
4. Done! Your photo set is now ready to upload and sell
