Hey, you know that button above the backspace key? Yes? No?

Yeah, that one.

Your answer may depend on how often you look at your keyboard.

Anyway, I’m not going to teach you how to use that button. Why? Because this website is for fun, and tutorials aren’t fun. Instead, I’m going to show you some fun and easy ways to share pictures with your friends using one of 2 very small programs called Gyazo and LightShot.
Now, for those of you that are simple, impatient, or in a hurry, Gyazo is a fairly quick program to use. As shown on the website, you just use your mouse to trace a box around whatever you’d like to show that friend of yours, then — BAM. An image is created, and a link to it is automatically copied to your clipboard. I’d suggest pinning it to your taskbar for easy access.
Second on the list is LightShot, which is pretty similar to Gyazo, but with the option to upload, edit, and search for similar images. Either way, the choice is yours.
