@mworley, That was NOT intended to be a d!ck response. I apologize if it came across that way and it offended anyone! My brevity sometimes gets me in trouble.
I have been working with a non-technical person right now and I am trying to show her how to find this kind of stuff out for herself. My experience is that if people know of these little tricks and are self sufficient, they get a lot more satisfaction and are more productive. Most non-technical people would not even attempt to try this and they should IMHO. Using the inspector is useful far beyond just finding image sizes, it’s good for finding the sizes of text, parallaxes any element for that matter.
Anyways Happy Holidays to you @mworley!
