Displaying png/jpg image with ruby tkextlib/tkimg - image not found

I have trouble displaying png/jpg image with ruby and tkextlib/tkimg

require 'tkextlib/tkimg'
root = TkRoot.new
root.title = "Window"

image = TkPhotoImage.new(:file => "/path/to/image.png")

label = TkLabel.new(root)
label.image = image
label.place('height' => image.height,
        'width' => image.width,
        'x' => 10, 'y' => 10)
Tk.mainloop

the error:

/Users/dragon/.rvm/rubies/ruby-2.2.4/lib/ruby/2.2.0/tk/package.rb:86:in `rescue in require': TkPackage dlopen(/System/Library/Tcl/8.5/Img1.4/libtkimgwindow1.4.dylib, 10): image not found (RuntimeError)
from /Users/dragon/.rvm/rubies/ruby-2.2.4/lib/ruby/2.2.0/tk/package.rb:83:in `require'

from main.rb:1:in `<main>'

The code works with any *.gif type image but with jpg/png type of image it gives me the image not found error, but I'am 100% sure that the image exist at specified path.

also, tkextlib/tkimg should work with that types of images.

please help. Thank you.

ruby 2.2.4, os x: 10.11.6

also there should be no problem with priviledges as the image displays in similar code in python.

I tried to google a bit, but the code shown up should work.

also, is there any other way to display jpg image in ruby?

Your code works fine on my computer, for either jpg or png, with absolute or relative path. Do you have any "weird" character in your path name, like a whitespace? To be sure, you could try :

image_path = "/path/to/image.png"
puts File.exists?(image_path)
image = TkPhotoImage.new(:file => image_path)

ruby 2.0.0p481 on Mac Os X 10.9.5
