Display the actual resolution of images on top of images, excluding images smaller than a specified size. Works on regular pages and direct image links in Firefox.
what it does:
the script sees the images resolutions and displays them on the right top corner
*note:
I decided that I don't care about images smaller than 300x300, you are welcome to change that behavior
my reasons for the script:
I made the script for myself, to be able to see the resolutions of images because I didn't found a simpler solution
