How can I browse photos on iPhone in Mac OSX? Previously, on Windows, iPhone was recognized as a camera and I could browse image folder with Explorer without a need to import/download/tranfer photo files to the computer.

Is there a way to do the same on Mac OSX? I mean, all approaches I have ever read are somehow connected to import procedure (iPhoto, Preview, iTunes, etc.) or to hacking the iPhone and installing some apps that will allow to mount the phone as storage drive work. 

What is the easiest and most straightforward way to view that files without transferring them to a computer?
The Image Capture app allows you to browse the iPhone's photos, albeit not at full size or resolution, without first downloading the image files to your computer. Image Capture also gives you the tools to download all or selected subranges of the photos on your iPhone, as well as deletion.
