Your printable cards will come to you as an attached jpg file through the email. A jpg file is a common image format that is compatible with pretty much every computer.
In the email, the attached file usually appears at the bottom of the text, but it may vary depending on the type of email you have.
The image of the printable card itself may even appear or just the name of the file. In any case, you should have several different options of what to do with the attached file.
One of the options is to download the file. This option may appear as a download symbol or the words "download file" or both. Click on this option. It is usually a link that tells your computer to download it. Your computer may ask you if you want to continue to download it. Yes, click on the correct response to the answer and follow through with the download. It should only take a few seconds.
Your computer may ask you where you want to save the file either before or after you download the image. I recommend saving it into your Pictures into a special folder named "JOYFULcards," for example.
You will have to do this with each attached file.
Your may have to create this folder before you download it. Just go to Pictures, and at the top of the Picture box there should be an option that says something like "new fold." Click that to create a new folder for your cards.
