First, Resolution (as the term is used by Adobe - i.e. DPI) has nothing to do with it. All that does is change the number.

Note - I'm using CS4.

- Resize your image to 800 pix max using Image>Image Size.
- Convert to sRBG if you use something else
- Convert to 8-bit (in CS4 the jpg option is not available if it is 16 bit, CS5 may be different)
- File>Save As
- Choose JPEG
- Hit the Save button
- A JPEG Options box opens
- Check the Preview box. Right under the box it will show the saved file size.
- Adjust the Quality until this file size is less than 293K (for this forum)
- Hit OK.
