This document provides instructions for three image editing techniques in GIMP: blending images, removing backgrounds, and changing the color of clothing in an image. To blend images, the user opens two images as layers, adds a layer mask, and uses the gradient tool to fade between the images. To remove a background, the fuzzy select tool is used to select the area to keep, and the alpha channel is locked and deleted. To change clothing color, the user outlines the clothing with the paths tool, desaturates the layer, creates a new color layer, fills the selection with the new color, changes the layer mode to overlay, and blurs the edge.
