Printing An image in Higher Resolution

[egkey]

Hi, I need to know how I can print an image in a higher resolution. I am using floorplan images in a brochure, so I export the images and save them as pictures. However, the pictures cannot be saved larger by zooming in, becasue only what appears in the actual browser window is what will be saved as the image. I just need to magnify the image becasue it is too blurry. Any suggestions?

For floor plans, you could try exporting an .emf instead.
