Slow down, take a deep breath, and perhaps read the Help, or look at some of the Switching material on the Apple website.
'm used to filing photos fairly easily on my PC. e.g. create a folder, throw the photos in, done. When you want to locate your photos, they're always right where you left them.
The most basic form of filing: a the File System and an Image Viewer. Works perfectly well. And you can do it this way on the Mac too. You have a perfectly good file system called the Finder, and there are many, many Image Viewers for the Mac. Search on
MacUpdate.
iPhoto, on the other hand is a Photo Organiser. That is a database, with an image viewer built-in, lightweight editing and some other features. Like any database, it needs to to do ALL your work in the iPhoto Window. There is simply never a need for you to go rooting around in the iPhoto Library Folder.
Want to get to a file? There are three ways (at least) to get files from the iPhoto Window.
1.
Drag and Drop: Drag a photo from the iPhoto Window to the desktop, there iPhoto will make a full-sized copy of the pic.
2.
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.
3.
Show File: 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.
And FYI, A Note about the iPhoto Library Folder:
In this folder there are various files, which are the Library itself and some ancillary files. Then you have three folders
ℹ
Originals are the photos as they were downloaded from your camera or scanner.
(ii)
Modified contains edited pics, shots that you have cropped, rotated or changed in any way.
This allows the Photos -> Revert to Original command - very useful if you don't like the changes you've made.
(iii)
Data holds the thumbnails the the app needs to show you the photos in the iPhoto Window.
