If you have a mobile device - it can be used to create VERY high quality photos. If not, you can borrow a point and shoot camera from your teacher, or team up with another student if they're willing to share their device with you.
A photo taken on your mobile device can be sent through WiFi from your cellphone to your account easily -
Install GOOGLE DRIVE on your mobile device, and you can SHARE photos to your Googledrive with just a couple of taps. Then on your desktop browser, download the file to your P: drive and name it appropriately - move it into an appropriate folder as well.
ALTERNATIVELY - Send Photos to yourself through EMAIL from your device (SHARE) - then open up your desktop browser and DOWNLOAD the file - It should arrive in your P: Drive. Move it from there to an appropriate folder on your P: Drive and name it properly
Photos sent from your phone may USUALLY NEED to be UNBLOCKED in order to be submitted through HANDINS
