She's not a photographer nor a printer.  She just liked my photo.

I like the way Qimage interpolates small files to larger files.  I have a photo that I want to give to someone that she can print herself.  My original file is just too small to make as big as she needs it.  (The picture I printed and that she saw and wanted to make a larger version of was already cropped quite a bit.)  I don't have the capability to print 16 X 20 on my printer, so I'm willing to just give her the file.

Is there a way I can have Qimage interpolate my file and then save it to a flash drive to give to someone?
