Looking for a way to conveniently display photos from your iDevice to a computer without the need to import your images or install some kind of desktop client software? Showtime by Aptogo is the app for a painless photo presentation.

Use it when visiting friends or relatives, and even on your own computer to transfer just one or two photos without digging out your Dock connector to USB cable. Showtime can also be used in a school or business environment for showing images to a group through a computer connected to a large display, HDTV, or projector. You could even have a room of students or colleagues all connect to the app using their laptops.

How does Showtime accomplish this without additional software? The iOS app creates a dynamic web page, where most up-to-date browsers are supported. In fact, Showtime has been tested for compatibility with Internet Explorer 7 and 8, Firefox 3.6 and 4 Beta, Safari 5.0.3, Opera 11, Google TV, and Boxee.

Showtime has a number of features you should find useful. Choose between black or white user interface and background themes, pick any album or the Camera Roll from the iOS Photos app, display a single large or multiple photos simultaneously, download photos in original quality, and control the experience from your iDevice or the computer.

Within the Showtime app, you can tap on the small arrow in the top-right to show and hide slideshow controls and the multi-image or single image toggle switch. Multi-image mode continues to add photos to a gallery grid as more and more are selected (tapped). Changing albums and selecting photos on your iDevice provides instant updating on connected computers.

There are two ways in which to direct your desktop or laptop’s web browser to the Showtime app. Showtime will display your iDevice’s current local IP and the proper port to enter into your browser’s URL bar, or you can jump to http://go.aptogo.co.uk/iPhone while the app is open on your iDevice.

The Aptogo URL works with the company’s servers doing an anonymous IP resolution and rerouting, which seems to work quite well. You can change the device name and port, plus verify the bookmark and IP information within the Connection area of the Showtime app. If, for whatever reason, you don’t feel comfortable with the bookmark registration feature, you can disable it.

Showtime is designed for iPhone and iPod touch running iOS 4.0 or later. Showtime is being offered at a limited time introductory price of just $.99, 50% off of the standard App Store cost.
