You can transfer your photographs from your computer to a flash drive.
These devices are also called thumb or keychain drives.
Spend about $10, or thereabouts, for an 8 gigabyte (GB) or larger flash drive.
Flash drives can be purchased from photography stores, Amazon, Best Buy, Radio Shack, and the like.
• Select the photographs you want to show your classmates.
• Copy and paste (or drag) them to the flash drive.
