mark,
could you walk me through the steps to resize? I have been using photoshop "image size" but just can't seem to get it right.
thanks

Yes, here goes:
When you open the Image Size dialog box, the first choice you want to make is whether or not to resample the image. Resampling means that you change the total pixel count in the image. You need to check the "Resample Image" box at the bottom of the dialogue if you wish to change the total pixel count.
If you select to resample the image, if the pixel dimensions shown at the top of the box will be reduced (the figure at the left of the bracketed figure) chose BiCubic Sharper in the very bottom drop-down menu. If the pixel dimensions will increase, choose BiCubic Smoother. Now, if you change Resolution, which is pixels per inch, you can leave the dimensions the same or you can change them. If you reduce dimensions or resolution total file size goes down. If you increase them file size goes up. If you reduce one and increase the other, you need to see the calculated result to know in a hurry what happened. When you resample there is always some loss of image quality, but doing it once while maintaining a good print resolution is not visibly harmful.
If you select not to reample (leave Resample Image) unchecked, then if you increase the resolution the width and height of the image will be reduced so as to maintain the same number of pixels. If you decrease the resolution the width and height will increase to maintain the same number of pixels. Or put otherwise, without resampling if you increase the width and height the resolution will go down, and if you decrease them the resolution will go up.
So much for the mechanics. Which options to use depends...............another chapter if you want it!
