If you want to resize a picture (to make it bigger) without compromising the resolution try:
Image, Image Size. In the Image Size dialogue box, change the units from Pixels to Percent. Type 110% for the Width and Height. The Resample Image box should be checked and use Bicubic. Then you would repeat the command as many times as it takes until you get to the size you need.
