To upload a photo to myCIA, your photo needs to be 133 x 133 pixels. If you've never heard of these terms or are not sure how to do this on your computer, please review this How-to and either visit the 3rd floor techbar or rm 114 for photoshop access.
To add a profile picture to your myCIA, first go to my.cia.edu. Then log in with your myCIA credentials including your username (not including @cia.edu or @student.cia.edu) and password.
When you've logged into your account successfully, click the square icon on the far left.
In the menu that appears, click My profile & settings.
Next click My profile. Then click the carrot for My photo. Now click Replace Photo.
