"You yourself say that they are afraid of clicking the photo, therefore, what
you are asking of them is obviously _not_ the intuitive behaviour."

That does not mean that they are afraid to click the photo because it turns the
preview off. They are afraid to click anything, menus, toolbar... and even more
afraid doing a double click because they have no idea what difference is
between single and double click and when to do them.

Long time users can understand the basic difference of single and double click.
They can even reconize the difference between button and icon.

" In what other application does one click the main object to go back in the
history of actions?"

Almost all. You click to enable something in menu and you click again to turn
it off. You click on toolbar to fullscreen and again to return back. Single
click to back and worth. Not single click to enter somewhere and double click
to go back.
Even Konqueror has the option to turn on the single right click to go back in
history instead using the toolbar buttons.

The only difference example the Back/Forward icons and Fullscreen is that other
gives the indicator that you can turn the function off when clicking it again.
Like menu entries has the [X] checkmark in front of them telling the ON/OFF
function.

And we are still talking about mouse controlled user interface, not
touchscreen. On touchscreen it would be very intuitive and logical to pan view
when sliding finger over it.

And double click is more like "execute" or "Open" and not "close" or
"shutdown". 

If we brake up the idea of the Album view.

We are watching first thumbnails a small picture of the photograph. And we have
lots of them (depending the thumbnail size).

Why we want to click a photo? 
1) Preview it on bigger size 
2) Open it to editor.

When we do open it to editor, it comes to follow showFoto rules, what are now
that the area selection is on left click, pan is on middle click.

but if we open the preview, we get by default the bar of thumbnails as well.
The bar tells us that we can browse the photos as well from there.
But we have two questions here.

a)  How do I get back to album view?
b) How I zoom in?

How does user zoom in? He use the zoom buttons or slider at bottom of the
screen. Where are located other functions to view like previews, zooming
panning and warning indicators.

The Panning is secondary action after the zooming.
When we are at the first step - what was to get the big preview up - the main
question is how to get back (we can make a assumption we want to go the next
photo but it is as wrong as making assumption we want to jump to first photo or
select any other) to the album view. We can click the album again and it can be
intuitive function because it is one place where we change the main view. But
it should not be so that we need to click again the album and get jumped to
first photo. Getting back should happen by same way as we got there. Just by
stepping back.

We did first a single click to get a preview. Making again a click is intuitive
way to get back. But this is a case only when we do have a single click on
system. On double click functions the double clickin is the intuitive way to go
back.

And specially on the case where we have turned off the thumbnails bar on
preview or the statusbar, the mouse buttons turns to be more vital to functions
by intuitive way than what the GUI tells us (example this case clicking the
album turns to be intuitive if single click does not turn back to original
view). 

This questions is as well about how many buttons do we have on mouse and what
they actually do.

_Normal three button mouse:_
Left | Middle | Right

Left enters to preview and quits it.
Middle zoom In/Out and Pans
Right brings up the context menu.

_If we would have two button mouse:_
Left | Right

Left enters to preview and pans it.
Right brings up the context menu.
Right+Left zoom In/Out.
Double clickin quits the preview.

_Five button mouse:_
Left | Middle | Right
Back | Forward

Left enter to preview and close it
Middle zoom in/out and pan
Right click opens the context
Back and Forward moves to next/last photo

And these would be on single click system. The double click adds a new choise
to have a single left click to pan the view and not the default view button,
the middle click with zoom in/out function.

I can understand very well the double click to exit preview when having a
double click system. I have desktop computers in such way configured and other
advanced users who I know.
But on laptop what I mainly use with only a touchpad, the single click to
enter/exist is more intuitive when using just one finger. But when using two
fingers touchpad+mouse buttons that I can keep left click pressed, I wait that
I can do a selection like on thumbnails etc. And one reason _I wait_ next
thing, is that I have a multitouch capable touchpad. I zoom in/out with two
fingers and I pan with three fingers (middleclick) just like I would do with
middle button on my mouse. 

The whole single click vs double click question is a very huge and it depends
so much about what questios we do have in our mind, what we want to do and how
to reverse the actions what we just did and how we do not do mistakes.
