Creating an Image with Transparent Parts

If an image has transparent parts, some browsers will ignore them.  But, creating images with transparent parts is useful when making a collage or when creating a Visio diagram with embedded images.  Here is how to create an image with transparent parts using GIMP:

  • Install GIMP, if necessary.  Here is a link to the Windows installer for GIMP 2.8.2
  • Open the image, or copy/paste it into GIMP.  If it is copied in, save it before proceeding.
  • Choose the Layer -> Add Transparency -> Add Alpha Channel menu.
  • Click on the Fuzzy Select Tool icon:

  • Click on the area of the image that you want to be transparent.  Note that the area of the image that you want to be transparent must have a fairly uniform color.
  • Press Delete.
  • Repeat until you have removed all of the areas of the image that you want to be transparent.
  • Choose the File -> Export menu.
  • Save the file as *.png
