Methods for Photoshop
This is what helped me to remember how to use the tools.
To rotate image: Edit > Transform > Scale, Rotate
To resize an image: Edit, transform, scale
Merge image two images together: Open image goes to the image tab, Windows, Arrange, 2 up vertical, then to the right click on the background then, click on the layer from the background. Then drag the image to the main page, go on select then and click deselect.
