Hi,

I need to download an image, and I’ve mucked about with Net::HTTP

resp = Net::HTTP.get\_response(‘[www.mydomain.com](http://www.mydomain.com)’, ‘/test.jpg’)  
f = File.new(“test.jpg”,“w”)  
f.write(response.body)

And various other combinations using HTTP.get etc. Anyway, I get an  
image, but it looks very psychedelic. This is obviously not the correct  
way. I also don’t want to use Imagemagick for this.

Has anybody done this before?

Joerg

Are you on Windows? If so, you need to use:

f = File.new(“test.jpg”,“wb”)

See [http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/18810](http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/18810)  
for a discussion of why, and  
[class IO - RDoc Documentation](http://www.ruby-doc.org/core/classes/IO.html) for the documentation of  
this mode.

Also you are trying to write response.body into the file when you  
should be using resp.body because resp is the var you used to set up  
the Net::HTTP object
