how to view image properties in safari

Control click the page in Safari then click Inspect Element.

Select Images on the left.

Click through the images in the list. You'll see image properties on the right.

You're welcome.

For others that are looking for this option: You may need to enable "Show develop menu in menu bar" at the bottom of the Advanced options in the Safari preferences menu. Otherwise "Inspect Element" is not visible. Took me a while to figure that out, so I thought I'd share. Cheers.
