formating an image

[eeha]

I have a picture that needs to be formated for a documnent i need to send.
here is what they are asking for
grayscale in 8 bits color depth
or color 24 bits / 8 bits at a size of 240x360

the file shouldnt be more than 65000 bytes.

if i just make the image grayscale to the size they specified would that do the job?

Also how can you make a 24 bit image? in RGB the options are 8/16/32 bits!!!

and at that size why are they allowing 6 megs? thats HUGE
in 300 res the file is no larger than 127K!!

thanx for your help guys

maybe, because 6.5meg is their email limit.

Just make it grayscale and the size

A 24-bit image is RGB 8 bit. With 8 bits per channel, a 3 channel RGB file is 24 bits.

this might help

black & white (monochrome)  =>   1 bit
greyscale                   =>   8 bit (256 shades [i]see below[/i])
[red]R[/red][green]G[/green][blue]B[/blue]                         =>  24 bit (composed of 3 x 8 bit channels)
CMYK                        =>  32 bit (composed of 4 x 8 bit channels)

8 bit explained in binary:-

128 | 64 | 32 | 16 |  8 |  4 |  2 |  1
--------------------------------------
  1    1    1    1    1    1    1    1 = 256
