Creating a Zip File
Windows XP: Select the files that you want to Zip. You can select the entire contents of a folder by choosing the "Edit" menu and then "Select All".
After selecting the image, Right Click on any of the selected images. This will pop up a context-sensitive menu. Choose "Send to: " and then "Compressed File".
This will create a single file containing all the images you selected. When making your online order, simply "Browse" and select the Zip file you created and then wait for the upload to complete.
Windows 98/2000:
The compression utility is not built into Windows 98/2000 so you will need to download a program. WinZip is one of the most popular and get be download at www.WinZip.com. Once this is installed in your system, follow the directions above with the exception that you will choose "Add to Zip" from the pop-up menu.
Macintosh OSX:
Create a Zip archive of your images by holding down the Control key and clicking the folder containing your images. Choose "Create Archive of [your folder name]" from the pop-up menu.
or
Use a utility like Stuffit. A free demo can be downloaded at http://www.stuffit.com/mac/standard/. After this has been installed select all the photos you want printed and drop them on the “DropStuff” icon with the Zip option highlighted. This will create a file with a name like “pictures.jpg.zip”. You must then remove the .jpg part of the name. So the file name is “pictures.zip”. Select this file(pictures.zip) after clicking the browse button. Finally click the upload button and view your order.
