1: Open the email. If the images show up in the email (you can visibly see them), right click on each picture and click "save as". Chose a place to save them to and remember where that place (desktop is a good choice). IF you cannot visibly see the pictures, there should be something that says "Attached images". There you should be able to download the pictures by clicking on their links and clicking "Save as", follow the procedure above.
2: Insert your CD into the CD drive
3: If you are using windows XP/Vista - Click on start >My computer > there should be an option for "CD" such as "Audio CD" or "DVD CD" or "CDRW". Right click on the CD and click "Explore".
4: You should have a new folder open.
5: Click and hold down the left mouse button, select all of the pictures wherever you saved them. They should be highlighted in blue, right click on any of the files and click "copy".
6: Right click inside the CD folder and choose "Paste".
7: Wait for the files to be copied, and voila!
