Screenshot save into iphoto library?

He means that screenshots can't be said directly to an iPhoto library. It has to be saved to the hard drive and then imported into the library. If a an image file/screenshot was saved into the iPhoto Library package it would not be recognized by the library.

As TD said, you can create an Autoimport folder for iPhoto with Automator. I described the procedure here for Photos: Automator Service for an Auto Import Folder for Photos

This workflow will add a folder action to import any photo dropped into the watched folder into Photos.

Just replace the action "Import to Photos" by "Import to iPhoto" in the workflow, if you rather want to import into iPhoto.

But first you have to change the default location for the screenshots to a separate folder, where you attach the folder action to. You will probably not want to find any document you drop onto your Desktop in iPhoto. I created a folder named Screenshots in my Pictures folder for this.

Change Where Screen Shots Are Saved To

If you take a lot of screenshots you know how fast your desktop gets littered with them. The best solution is to create a new folder in /Pictures/ or ~/Documents/ and then set that to the new defaultscreen shot save location with a defaults write command:
defaults write com.apple.screencapture location ~/Pictures/Screenshots

Change the Default Screen Shot Image Type

Speaking of screen shots, you can change the default file type from PNG to JPG or a variety of other options with a defaults write command. JPG offers the best file size and compression while still looking decent:
defaults write com.apple.screencapture type jpg && killall SystemUIServer

I I click shift+command+4 then grab the shot by dragging the little plus across the area i want to save. Then from the desktop I drag that shot into iPhoto and it changes into a JPG there. Hope that helps.

no -- you do not "save" to iPhoto you save and then import to iPhoto - it is a database program and only opertes with photos that have been imported to the iPhoto library

What did he mean by that answer?!

You could create an automator workflow to automatically import the image from the desktop or wherever you save it to.
