Subject: Load and Embed an Image Using Ruby?

Hello,  I'm trying to load an 8x8 GIF file and embed it directly into some 
HTML but the image pixels are out of order and the dimensions are not 
correct.  I assume the problem is with the byte order during the read.  Can 
any of you suggest a better way to do this?

require 'base64'

gif_path = 'C:\work\gifTest\gifTest.gif'
html_path = 'C:\work\gifTest\gifTest.html'

f = File.open( gif_path, "rb" )
data = f.read
f.close

encoded = Base64.encode64( data )

f = File.open( html_path, 'w' )

# links work perfectly
f.puts( "<IMG SRC=file:///C:/work/gifTest/gifTest.gif>" )
f.puts( "<IMG SRC=file:///#{gif_path}>" )

# something appears, but out-of-order and wrong dimension
f.puts( "<IMG SRC=\"javascript:'#{data}'\">" )

# these produce the "missing image" placeholder
f.puts( "<IMG SRC=\"data:image/gif;base64,#{data}\">" )
f.puts( "<IMG SRC=data:image/gif;base64,#{data}>" )
f.puts( "<IMG SRC=javascript:'#{data}'>" )

f.close
