Windows 7 - image pixel dimensions when hovering over an image

I hope I'm wording this correctly. I was wondering if there was a way to see image pixel dimensions when hovering over an image in windows 7. This is a standard function in XP, but in 7, it only happens off and on. I do a lot of web design and would like to have that quick info when hovering over images. Otherwise I have to right-click, choose properties, and then choose details. I attached a screenshot of what I'm talking about. Thanks!

Just click on the picture, all details including dimensions will appear in the Details Pane (located at the bottom)

Or just hover over the image without clicking it and the details will appear

I appreciate the reply, but hovering over the image doesn't always work. It only works once in awhile. I was hoping there would be some setting I could change to make it work consistently.

Hovering over the image works just fine, the point is to give focus to the folder the image is located in. For example, if you have an image located on your desktop, and your browser window open: hovering over the image while the browser has focus won't display these details. However, if you click on the desktop, then hover over the image, the details will appear. Same thing for multiple opened folders.
