Judging by the number of users on this gadget (764,697) they must be doing something right.  This gadget is a classic photo feed that gives you new travel photos with each page refresh.  The photos are pretty nice, but there are two pieces missing here 1) none of these photos are available in high-res, probably because the authors just grabbed them off image search somewhere and 2) the gadget has none of the features we’ve come to expect with online photos like sharing, commenting, tagging etc.  Clicking on an image takes you through to “etravelreviews.com,” which looks like it could use some work itself.  The inclusion of a Google custom search for travel looks like it’s geared toward monetization rather than adding functionality, but might be useful for some users.  Bottom line, good for eyecandy but not much else.
