Problem:
With the small size of thumbnails, when there's only one single thumbnail image in the middle of text on a page, it's often hard to tell it's an image. And the visual presentation is somewhat strange.

What we do currently:
Add the text 'click to enlarge' manually as part of an image title as shown in the screen capture.

Improvements:

• Thumbnails are displayed with a magnifier on top automatically.
• One step further: Users can view the original image by hovering the mouse over thumbnails after a certain amount of time, say 0.5 or 1 sec, instead of having to click them.
