I want to design a website.
I've got some images with different w*h.
For example, we have lots of pictures at 800*600 or 1024*768 or something else.
In our website we have some restricted frame like 270*160 or 512*900. We want to scale or resize the main pictures in restricted frame size.
How we can do this with Photoshop or any web design tools to resize images without stretching, destroying, or cropping the main images to properly fit into frame size, ?
