Hi everyone,

I've got a bit of a problem that I desperately need resolving within the next couple of hours:

I have a 420x420 pixel JPEG that currently has a 128kb file size. The problem is that it MUST be under 100kb (it must also be a JPEG and 420x420 pixels - no more, no less). - These are the restricions I have to adhere to - the photo is to be used for an ID card for a family member.

I'm using Photoshop 8 CS for Mac OSX. Upon saving, it asks you to choose image quality on sliding scale from 0 to 12, saying that the lower the number, the lower the quality of the image and the file size.

- On "12", the image is 240kb in size,
- On "7", the image is 128kb in size...

...but here's the bit I can't understand...

- Below "7", the image doesn't get any smaller than 128kb.

Can somebody please help me to break the 100kb barrier?

Many thanks in advance,

Clive
