Hi, anyone knows of an app that can allow me to apply pre-defined tags to photos so I can easily filter based on the tags later on? I have over a thousand photos that I need to present to someone to choose on an iPad to be printed later. I need to be able to dump the chosen photos onto a USB stick afterwards. Tagging appears to be the easiest way to do this, unless someone knows of a better way. Unfortunately I am unable to install iPhoto on my iPad 1 so this is ruled out.
