If you are just going to load the pictures into your PC, that is fine. But, if you decided to share the pictures with your friends in Facebook, you're going to have some problems. It will not be practical to upload the full sized pictures as it will take quite some time to upload all 4GB of goodness. So what you can do is to resize the pictures to a reasonable size (say 800x600 or 0.5MP) for upload. Of course, you could fire up your faithful image editor like Photoshop, GIMP or MS Paint to do that, IF it was just a handful of them. But 1600 images? You have got to be kidding. One way of course is to have scripts to batch process it, if you're fluent with scripting on Photoshop, but here I'll recommend some software that will make your life easier.
The first ever free image resizer I got introduced to is the "VSO Image Resizer". It does a brilliant job of batch converting images to the size that you want. And in addition, it lets you alter the EXIF data, add watermark and perform batch rename. One downside though is that it has an annoying pop up every time you launch the program until you buy and unlock it.
Lately I've found another great resizing tool that's also free, called "FastStone Photo Resizer". It pretty much have all the features that VSO has, plus some more. And one thing I liked most about it is it has a portable setup option. I'm a big fan of portable apps as you can dump the whole app folder into a thumb drive and bring it around to be used on other machines without needing to run the whole set up process.
And there you have it, Image/Photo Resizer apps that saves you tonnes of time and makes your life easier.
