How to delete multiple photos

This is a Finder question rather than an iPhoto one but this might help:

This is the same all through the OS:

To select more than one file: hold the command key when clicking on the second and subsequent files

If the Files are contiguous: Click on the first, hold the Shift key and click on the Last then all the files between will be selected.

Command-backspace will move whatever is currently selected to the trash.

While at the Desktop type Command+A to select all items and drag them to the Trash. Open the Trash and drag all items you don't want to delete back to the Desktop. Then empty the trash.

In the future if you plan on exporting lots of photos to the Desktop always create a new folder to export them to. Each item on the desktop is considered to be a Finder window. Too many of them can bring the Finder to its knees. Users have reported that accidentally dumping a great number of photos to the desktop has frozen their Mac. They had to reboot their Mac into Target Disk Mode, access it from another Mac in order to move all of the files from the Desktop into a folder.

One thing to watch out with that method is if you have drives on your desktop, they will also be selected and some will be ejected (external) others will create errors (system). Much better to go to your users folder and open the desktop from there (Users -> "Your user name" -> Desktop). This way only documents will be shown.

To select multiple photos, if there are lots in a line you can either click on the first AFTER the file name and while holding down the mouse button drag down, or click on the first then shift click on the last in the list. If there are files in between you don't want to delete than hold down the command (cmd) key while clicking on each file to be deleted.
