need help enlarging a picture
I need help for a friend. She has downloaded a bmp picture on a message board of her family, but the picture is so small (something like 175x223). I copied it to my computer and changed it to a JPEG format in Adobe Photoshop, then enlarged it, but it's really blurry. I even downloaded RealJPEG and changed the format this way, but it's still blurry.
How can I change a BMP format to a JPG and enlarge it without it being blurry?
