you can't make the file size smaller unless if you take out some stuff from your constructed bebo skinHow do i change the ';file size'; on photoshop?
if you are saving as a jpeg then you have two options to decrease the file size.





First is to go, Image, Image Size - and change the size by scale or pixels Keeping the proportions the same.





Or when you save a jpeg you have a dialog box that asks the quality on saving 12 being high 1 being low so this scale can be changed to say 8 and then the file size will decrease with the quality.
in photoshop menubar go to Image %26gt; Image size


Then resize your image.


and when you save your file go to file %26gt; save for web and devices





from that you can get a small file sized image.
