"Label 59 is a web application that lets you label anything interactively. It is ideal for creating engaging presentations that have interactive labels attached to them. These labels are hotspots on the photo and are represented by markers. You then define content for each of these markers by adding connectors, arrows, tooltips, text blocks and details window.
What you get as a result, is an impressive presentation (in Flash or HTML5) that highlights the key points on your photo when markers are clicked or when the mouse pointer hovers over them.
