Sometimes I use Bridge to look at images, and from there I decide which ones to import into Lightroom. It is then easy to simply drag the images over into Lightroom.

• Size your Bridge and Lightroom windows so that you can see both.
• In Lightroom, go to Library Grid view (shortcut G). It does not matter what folder or collection of images are showing.
• In Bridge, select the images you want to import.
• Click and drag from Bridge over onto the Lightroom grid (thumbnail area). Let go.
• The Lightroom import dialog will open. Specify import options as usual.
