Sure,
Here are some screen shots. The first one is when the table view appears. The second one is almost one screen scrolled down. All the pictures are larger than the image view displaying them but setting the scrollview zoom scale properly, each image fits in the scrollview. The 3rd screen shot is showing the first cell almost at the top, the one originally with the sunset. As you can see, the image is zoomed all the way in even though there was no double tap on the image.

Not too sure what is happening. I have an NSLog() statement that prints the zoom scale of the scrollview when the table asks for the cell at a given index path and the zoom scale is the same all the time, but, obviously, it is not.

I check the zoom factor in tableView:cellForRowAtIndexPath: when I configure the cell that the UITableView is requesting and maybe I'm missing something, but in each case, the zoom scale factor seems to be the same. However, on screen, the image is clearly zoomed quite a bit. I started off from the TapToZoom project part of the ZoomSuite sample.
