How to Install Gimp Brushes

Creating a Brush

1. 
   Create the image you want as a brush. Use GIMP to draw your brush for you. It can be literally any image, but some work better than others. A brush will basically make a stamp of the image over and over in rapid succession as you move the mouse, so complex can create an undesirable effect where the intended image is obscured. Open the file with appropriate settings for the size and shape of the brush you want. Use black pencil to draw the image, and zoom in to ensure you get a pixel-perfect shape. ^{[3] X Research source}

   1. Note that you can also just copy a selected portion of the image, and GIMP with create a brush from the selected area for the current window. You'll have to save the selection as a brush for it to remain available, however.
   2. For a simple brush with variable colors, use black for the brush itself, and pure white for any transparent spaces. You can select the color of this type of brush via the normal color selection process, and draw using its shape in any color you please.
   3. For a brush that cycles through shapes or colors, you will need to open a file with transparent fill. Make each different image you want the brush to cycle through on a separate layer. When you draw with it, each time the brush repeats the image it will use only one of the layers, giving you a closely repeated pattern as you draw. The colors of this type of brush are set when it created, so unlike variable-color brushes, you can't select a different color from the color selector before drawing.
2. 
   Save your image. Use the '.gbr' extension for simple brushes, '.gih' for brushes that cycle through images. Save it to 'C:Documents and Settingsmyusername.gimp-2.6brushes', or the analogous folder for your version of GIMP.
3. 
   Click the 'Refresh Brushes' button. This is a button near the bottom right of the brushes display that shows two arrows, each pointing at the beginning of the other. This should cause GIMP to detect and display your brushes. ^{[4] X Research source}
