If you have hundreds of photos on your computer and want to organise them using iPhoto - you'll probably be banging your head against the nearest wall in no time. The fact alone that you have to import your photos into the application before organising them makes iPhoto an inconvenient app to use.

If you want the organisational changes that you made to your albums and photos to be reflected in the Finder, then iPhoto certainly isn't the app for you. If you're looking for a more convenient way to organise your photos, the free Mac app, Lyn makes getting the job done very easy.

Its intuitive and easy-to-use interface will have your photo library organised in no time at all, making it a great alternative to iPhoto. Photos can be displayed in one of three ways. As large thumbnails:

As small thumbnails, with a large preview of the selected image:

Or as a list of very small thumbnails and the photo's EXIF data:

When viewing large or small thumbnails, you can easily access the photo's EXIF data in a convenient sidebar, by clicking on the blue information button in the top right hand corner of the screen.

While there is no one-click way to import all of your photos from a camera to Lyn, you can still access all of the files from the camera and do a quick drag-and-drop to get the job done.

Opening any given photo allows you to zoom in and out, show the image's actual size, rotates the image, and opens it in full screen, amongst a few other options.

Lyn's strength is in its layout. The menu of directories and folders makes it much easier to drag and drop images from one folder to another.

The application gives you full control when organising your photos as you would want them in your folders - a feature that is sorely lacking from iPhoto. Any change made in Lyn is reflected in the Finder.

Create new folders, move and delete images quickly from the comfort of one screen without having to switch from one Finder window to the next. If you need to locate the image in your Finder, Lyn makes it as easy as possible.

While it is possible to delete images directly from within Lyn, using the keyboard shortcut, CMD-Delete, you can't delete folders. That said, it is a small inconvenience as you can easily do this from the Finder. Another con to using Lyn is that it displays all files in any given folder, whether or not they are images.

Lyn supports a wide variety of images, including JPEG, TIFF, PNG, animated GIF and Raw. The app also allows you to display beautiful full screen slideshows of your photos.

Lyn's preferences are limited mainly to the way that it displays and opens images, as well as the general display of the app's fonts and colours.

Lyn is in public beta until December 1, 2010, so hurry up and download it while you can.

If you are looking for some some basic editing features, along with the ability to organise your photos, then Picasa is your best bet. Not only does it give you an easy way to organise, Picasa also has the added advantage of allowing you to sync your photos to your online Google account, giving you a quick and easy way to back up your images.
