Image Sizes of Thumbnail Images

In the past when using Dreamweaver I was told to make images thumbnails small rather than use settings to shrink a larger image. Does this hold true with RW?

@bruce, I would have to say yes it still holds true, the reason is when scaling down an original image, you are still consuming the larger bandwidth. By creating and using a Thumbnail, you reduce file size and decrease page load times.

My Practice is to make a Thumb, Small, Med, Large of each image for use in various circumstances.
