Question

Answer 1

file -> save for web

then play with the different optimization functions to achieve the desired preview and then save.

Answer 2

if for example image is larger in size 4x6" with 300 resolution,

and you need to make smaller, you can try both lowering resolution to half or %, and/or lower size to 2x3" or %, then check kb, there maybe other quality option for constrain resample and ratio in photoshop,

If the picture is too big and it is a .bmp you can try saving it as either a .jpg or .gif.
