Downloaded and installed version 1.0. No icon buttons are displayed, although the text after the button is. The Facebook like buttons do show if selected. There are images in the button folders. Permissions on the images set to 644. The plugin does not identify my Google tracking script – the script is working ok.
It appears that you have the width and height of your images set to 0, which is likely the cause of the problems : )
In the Trackable Sharing admin, there is an option “Button Size” — you can scale the button size there by entering dimensions, such as 24×24, or a percentage, such as 50%. For the default size, leave it at 100%.
Try entering a non-zero size there and see if that clears it up!
