Can't set smart album pictures as desktop backgrounds.

Question

i have imported 'without copying to library' a whole bunch of pics into iphoto and have created smart albums. now i went to 'change desktop background' by control clicking on the desktop and am selecting a pictures from one of the smart albums but its only displaying a blue background. this is true for all smart albums and normals ones as well. when i select an image from the other folders they work fine. what could be the reason?
the primary reason of importing stuff to iphoto was so that they are easily available across applications.

Do you know of any reason why the Desktop pref pane should not be able to use photos in a "referenced" iphoto library
It's just the nature of the beast.
but I just don't trust it enough to do what it will with my photos by having them stored in the iPhoto library.
What are you afraid of?
When you import a pic into iPhoto in the default Managed mode all it does is make a byte by byte copy of the pic. Nothing else. It's an exact copy. It makes no alterations, adds nothing, removes nothing.
The pic is stored in the Finder. Yes, it's in a Unix Style Package file, but apart from all the ways to access your pics I'll describe in a moment, if you want to look inside the package you can do so at any time: Simply right click on the iPhoto Library and select 'Show Package Contents' from the resulting menu. A Finder window will open and you'll see the Library inside.
There are various files, which are the Library itself and some ancillary files. Then you have three core folders
Originals are the photos as they were downloaded from your camera or scanner. (As your Library is referenced the files will be aliases rather than the actual files.
(ii) Modified contains edited pics, shots that you have cropped, rotated or changed in any way.
(iii) Data holds the thumbnails the the app needs to show you the photos in the iPhoto Window.
Remember: iPhoto depends on the structure as well as the contents of this folder. Moving things, renaming things or otherwise making changes will prevent iPhoto from working and could even cause you to damage or lose your photos.
Running a referenced library has a number of pitfalls - apart from the fact that System Preferences cannot use the files.
1. Import and deleting pics are more complex procedures
2. You cannot move or rename the files on your system or iPhoto will lose track of them on systems prior to 10.5 and iPhoto 08. Even with the later versions issues can still arise if you move the referenced files to new volumes or between volumes.
3. Most importantly, migrating to a new disk or computer can be much more complex.
Always allowing for personal preference, I've yet to see a good reason to run iPhoto in referenced mode unless you're using two photo organisers.
If disk space is an issue, you can run an entire iPhoto Library from an external disk:
1. Quit iPhoto
2. Copy the iPhoto Library as an entity from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.
If you're concerned about accessing the files, there are many, many ways to access your files in iPhoto:
For 10.5 users: You can use any Open / Attach / Browse dialogue. On the left there's a Media heading, your pics can be accessed there. Apple-Click for selecting multiple pics.
Uploaded with plasq's Skitch!
To upload to a site that does not have an iPhoto Export Plug-in the recommended way is to Select the Pic in the iPhoto Window and go File -> Export and export the pic to the desktop, then upload from there. After the upload you can trash the pic on the desktop. It's only a copy and your original is safe in iPhoto.
This is also true for emailing with Web-based services. If you're using Gmail you can use iPhoto2GMail
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.
Or, if you want to access the files with iPhoto not running, then create a Media Browser using Automator (takes about 10 seconds) or use THIS
Other options include:
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.
Your choice, obviously, but best to be aware of all the ramifications. By all means post back if you require more info.
You can set Photoshop (or any image editor) as an external editor in iPhoto. (Preferences -> General -> Edit Photo: Choose from the Drop Down Menu.) This way, when you double click a pic to edit in iPhoto it will open automatically in Photoshop or your Image Editor, and when you save it it's sent back to iPhoto automatically. This is the only way that edits made in another application will be displayed in iPhoto.
Other information that may offer comfort:
Events in the iPhoto Window correspond exactly with the Folders in the Originals Folder in the iPhoto Library package file (Right click on it in the Pictures Folder -> Show Package Contents).
You can move photos between Events, you can rename Events, edit them, create them, as long as you do it via the iPhoto Window. Check out the Info Pane (wee 'i', lower left) the name and date fields are editable. Edit a Event Name using the Info Pane, the Event Folder in iPhoto Library/Originals will also have the new name.
Mind you, I don't suggest that you change over in one go. I think the best thing to do is create a new Library (Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Create Library') and set it as a Managed Library. Import 50 or 100 pics an explore it, see how it works and see if that does anything for your confidence.
