There are a number of plugins that are designed to increase the resolution and/or size of an image cleanly. I use Stair Interpolation by Fred Miranda, which is a Photoshop Action and very, very reasonably priced. If you have more to spend, there's also Genuine Fractals, Qimage's Lanczos, and S-Spline, but I don't know much about the latter two. I have used the Genuine Fractals plugin and it's very good, but quite pricey. More information on Stair Interpolation via the attached link, including visual comparisons to enlargements and enhancements done with other plugins. bonni
