another update so soon you ask?

The main difference with this version is I removed the getter and setter functions for ITPC metadata and created the functions:

- getMetadataKeys( type ) - setMetadataKeys( type , keys )

Why did I do this?

Because every digital camera stores some type of it's own meta data. To get access to this you can call:

So what you can do is set the default keys (to empty string) like this:

That way you don't need to worry about lots of "structKeyExists" calls! :-)

Hope this makes sense, and any feed back will be welcomed!
