gimp basics

1. GIMP is the programme I'm mostly using and I think it's relatively easier to use compared to photoshop and photoshop's not free, so... Anyway, you can download GIMP here: https://www.gimp.org/downloads/

2. You'll see 3 windows after opening GIMP.

3. Click on "File" > "New" and this window will appear:

Set the width and height that you want, preferably not too small (or too big). I usually set mine to be 640px X 640px so it gives me space to decide how I want to crop it later.

4. You'll see this at the bottom of the middle window:

Zoom in or out by changing the value (currently at 66.7%). You can use one of their preset values or you can also type in your own value. The higher the value, the more zoomed in it'll be and 100% will show you the actual size of your canvas.

5. Click "File" > "Open as Layers" to open the pictures you want to use OR you can also drop the pictures from your file into GIMP directily.

#NOTE: Your canvas is the white square/rectangle, don't drop your image outside of the canvas.

OR you can drop your picture onto the layer panel as well.

I prefer dragging and dropping over "File"
