Generally image taken at digital camera is too large. Unnecessary it takes lots of space in hard disk and takes too much bandwidth while uploading in web. I was trying to find how to resize image and reduce the image size. There are lots of ways to do this. I just got a way to do in photoshop. Really photoshop is a wonderful software to play with image.
Just open the image in photoshop. Goto Image -> Image size. Check Resample Imge. From the dropdown select Bicubicle Sharper (best for reduction)
Now reduce the width as your wish and save it. Your image will be reduced as you want. Simple but useful trick 🙂
