At the top of the window, in the window manager title bar, you'll see, e.g.
  (clean socks.png (8bit indexed)
meaning the image uses a fixed "palette" of colours. You can edit the palette directly, or for more creative 
changes, convert the image to RGB with image/mode/RGB and then you can use as many colours as you like - but 
some video cards, especially ones more than 20 years old, may have problems. Those systems can't display most 
Web pages either.

My telepathy skills are on the blink today so I'm not certain which exact plugin it was or what exactly went 
wrong. However, GIMP is a pixel-based image editor, and SVG is a vector format. Use Inkscape to edit or 
create SVG.
