This debut app from Dove Valley Apps works as a fun search tool for pictures from public image feeds like Flickr and Picasa (Google Images is supposed to be added soon). The navigation of this free app is basic and easy - you enter a tag and a slide show of the images found appears on the screen. Furthermore it allows you to email images, save them to your photo album or send them to photo app iToony or to social networking app Twinkle.
This is great fun if you just want to search for some random pictures. For a slightly more serious search on the other hand this app is missing important features that would allow you to see the number of pictures found per tag and provide an overview of images. For specific searches it is therefore not a good tool to use but for anyone wanting to browse for fun or looking for new wallpapers for their iPhone The Tag Show is great.
