I've been working on this plug-in to be included in an iFrame on a real estate investor website. However, I am torn in the decision of how to provide the user with the action of viewing the full size version of an item. I am currently using a lightbox, which is not 100% complete at the moment; however, the real issue is the action item for the user to click to trigger the full-size view.
Currently, the user can click on the image and it will open up the lightbox with the enlarged version. However, I can't help but feel there is a better, more intuitive way in providing the user to access this view. Currently, there is no call to action. They just have to hover over the image and realize it is a link. Granted, I could note "Click image to enlarge" somewhere on the page, but I am open to something a bit more original. Possibly an 'enlarge' icon in the upper right of the image?
What do you feel is an intuitive method of providing the user with a means of enlarging an image?
You can view the interface in my testing environment.
