Question

I guess this is easy, I seem to be missing something simple.
I need to read an image and then display it which i do as follows, I should skip the code if the image is not available.

 stu_image ="/admin_num.jpg"

 if !stu_image 
         code for displaying the image
 end

But, this is not working. Could somebody help with this please.

Cheers!

Why not just testing if the file exists?

stu_image ="/admin_num.jpg"
FileTest.exists?(RAILS_ROOT + stu_image ) #  < rails 3.0
FileTest.exists?(Rails.root + stu_image ) # >= rails 3.0
