Even though you did not "download" the images to your computer, your computer still retained a record of you viewing the imagaes. This is just like if you went to a website and viewed child pornography images on the website - there would still be evidence of what you viewed on your computer.
It is against the law to view pornography depicting children. If you receive such an email, to not open the message, do not acknowledge receiving the message, simply delete it.
If you have been arrested for a child pornography related offense, it is extremely important that you seek the assistance of counsel regarding your rights and responsiblities.
