All you need is a computer and an internet connection.
You can use images directly from your computer as .jpg, .gif, or .png files for photo ecards. You can use .swf files for Flash ecards. Check out the dimension guidelines for the sizes that you want your ecard to appear. You can also use image editing software such as Photoshop to edit your images. If you don’t have Photoshop, you can even use MS Paint to write the copy onto your ecard.
You have the option of uploading the image without music: just leave the music field blank at the time when you are uploading your images.
You can upload .wav, .mid, and .mp3 files as the background music to your ecard. There are no restrictions to the file size. You just have to own the copyrights to the music or sound file you’re uploading. You can even record your voice and put it in your ecard! You need to embed the music into your .swf file if you’re uploading a flash ecard.
