Where is the iPhoto library folder?

Question

Hello,
I know this sounds kinda dumb, but I can no longer find the iPhoto folder that has my pictures in it. What I mean is, if I go to a Finder window and I click on "Pictures", it accurately lists all of my pictures that are on my MacBook Pro. However, there is no longer a folder there that I can open for my iPhoto pictures---instead, it's an icon of ALL of my iPhoto pictures. Does this make sense what I'm asking?
In other words, let's say I wanted to choose a single photo as my avatar for a certain webpage. Okay, so when the directory window opens up to allow me to navigate to the specific photo I want to use, in the past I have always clicked on "Pictures", and then I could see a FOLDER that I could click on to open it up. Once inside that folder, I saw the long list of picture categories (such as Events, Photos, Last Import, Faces, all of my custom folders, etc, etc, etc). But now, the only choice I have is to click on "iPhoto Library"---all 75 GB's of it! I don't want thousands of photos---I just want ONE. What happened to the folder that used to be there?
I am using iPhoto 11 (the latest updates are in it), Mountain Lion 10.8.1, and a MacBook Pro.
Thank you!

Directly accessing the iPhoto Library from the Finder is not supported, nor has it been on any version of iPhoto.
The First of these is what you want:
There are many, many ways to access your files in iPhoto:   You can use any Open / Attach / Browse dialogue. On the left there's a Media heading, your pics can be accessed there. Command-Click for selecting multiple pics.
(Note the above illustration is not a Finder Window. It's the dialogue you get when you go File -> Open)
You can access the Library from the New Message Window in Mail:
There's a similar option in Outlook and many, many other apps.  If you use Apple's Mail, Entourage, AOL or Eudora you can email from within iPhoto.
If you use a Cocoa-based Browser such as Safari, you can drag the pics from the iPhoto Window to the Attach window in the browser.
If you want to access the files with iPhoto not running:
For users of 10.6 and later:  You can download a free Services component from MacOSXAutomation  which will give you access to the iPhoto Library from your Services Menu.
Using the Services Preference Pane you can even create a keyboard shortcut for it.
For Users of 10.4 and 10.5 Create a Media Browser using Automator (takes about 10 seconds) or use this free utility Karelia iMedia Browser
Other options include:
Drag and Drop: Drag a photo from the iPhoto Window to the desktop, there iPhoto will make a full-sized copy of the pic.
File -> Export: Select the files in the iPhoto Window and go File -> Export. The dialogue will give you various options, including altering the format, naming the files and changing the size. Again, producing a copy.
Show File:  a. On iPhoto 09 and earlier:  Right- (or Control-) Click on a pic and in the resulting dialogue choose 'Show File'. A Finder window will pop open with the file already selected.    3.b.
b: On iPhoto 11 and later: Select one of the affected photos in the iPhoto Window and go File -> Reveal in Finder -> Original. A Finder window will pop open with the file already selected.
