Google has finally introduced the ability to perform reverse image searches. In other words, by using Google Images, you can find links to all the websites where the image was being used.

Recently I had a virus in my computer. If you have thousands of photos sitting on your hard disk, it can be quite a scary experience. Luckily, all my photos are double backed up externally on two hard drives.

If you are unfortunate enough to get a virus in your system, there are 3 very highly effective programs that should clean out your system and they are all completely free.

1. Spybot - Search & Destroy

2. Malwarebytes

3. Spyware Doctor

Install these programs on your computer and make sure they are updated. If you ever get a virus, reboot your PC and keep pressing F8. Then select boot up in Safe Mode. Once you're in, start running each of these programs one after another.

These should clean up most viruses in your computer.

Photo Sync allows you to download photos from your iphone to any computer using just your web browser and wifi connection. No cables are required. However, the iphone and computer must be on the same wifi network.

Just open your web browser on your Mac or PC and go to the we address (URL) shown on the iphone's screen when you launch the application.

This will load a web page showing all of the photos stored on your iphone. These images can be saved directly onto your computer by right clicking on the image and selecting save as. This app offers a handy way to download your photos without any cables.
