Didn't you get any software with the camera?,most digi cameras come with the editing software which alow you to resize,usualy in the image tab or image properties somewhere lol. You can easily resize them using windows paint too,usualy found in all programes (start up menu bit) then accessories and down to paint. If you use Windows XP, a useful and free download is the Image Resizer PowerToy, which allows you to right-click on an image in Windows Explorer and resize it immediately. also recommended is IrfanView, a fully-featured freeware graphic viewer program for Windows 9x/ME/NT/2000/XP/2003, which includes powerful image manipulation including a resize function.
