There is a simple way to manipulate multiple pictures within your photo albums if you’re using a BlackBerry 6 capable device. If you have a BlackBerry Torch, it’s even easier. Simply tap two photos simultaneously and you’ll get what you see in the image above. Hit your Black Berry button and you’ll have the option to choose what you want to do with your photos. If you have an entire load of photos…
you can easily delete them with a few taps.
In the image above, I have a few selected and I can do a few things within the options menu. 
In this image, I’m preparing to delete some unnecessary photos that I have saved from a BBM group. If you’re using a Torch, these are the steps. I’m not sure what you should do if you’re using a non-touch device, but, give it a try using the ALT key and selecting a picture. Hope this was useful for you…Enjoy your BlackBerry.
