Some might have wondered? How does the mega pixels affect the size of the photos? Well, I'm gonna to share what I've found out sometime back on this topic.

QVGA 0.077 320×240
EGA 0.224 640×350
VGA 0.3 640×480
SVGA 0.5 800×600
XGA 0.8 1024×768 sometimes called XVGA
WXGA 1.0 1280×800
SXGA 1.3 1280×1024
WXGA+ 1.3 1440×900
SXGA+ 1.4 1400×1050

WUXGA 2.3 1920×1200
QXGA 3.1 2048×1536
WQXGA 4.1 2560×1600
QSXGA 5.2 2560×2048
WQSXGA 6.6 3200×2048
QUXGA 7.7 3200×2400
WQUXGA 9.2 3840×2400

Its good to have a copy of the above information.

And a word of advice, in order for you to save space while uploading photos onto your website, its best you can convert your pictures to 800x600. Photos of this size will be less then 100KB, thus faster uploading and displaying on your website.

Check out these 2 softwares, VSO Image Resizer and FastStone Photo Resizer. Both are free softwares, plus the size is quite small, you can install it to your USB drive with no problems.
