Cropping or 'canvas size' allows you to trim your image to size without resampling.

Resizing allows you to scale your image with or without resampling.

To reduce pixel size, you must resample the image.

The 'levels' histogram is the best tool for adjusting tonal values of your
image. It may be better to do this during the scanning if the image has high contrast.

The 'colour balance' control is the best tool for adjusting colour values of
your image. In Photoshop, 'Variations' will show you a range of adjustment previews.
-
Use the 'unsharp mask' filter for sharpening of your image - preferably as
the final adjustment.
-
All the above adjustments may be applied selectively by using selection and
masking tools.

Text may be added in image editing programs use text in graphics thoughtfully
and sparingly, it is often preferable to create text in HTML.
