Properly-Sized JPG image file: All black-and-white .jpg images and color jpg images should be scanned at no less than 300 dots per inch and no more than 350 dots per inch, and within the pixel range suggested by the USPTO, namely, a length and width of no less than 250 pixels and no more than 944 pixels; e.g., a valid pixel dimension is 640 X 480 pixels. To ensure your image file meets these suggested sizes, you can use a free graphic viewer, e.g., Irfanview. If you cut-and-paste an image into Irfanview, or open an image file using the program, select "Image" from the tool bar and "Information" from the drop-down choices to view the current DPI and pixel dimensions. If your image is not in the proper dimension, you can use Irfanview to change the DPI and pixel dimensions: 1) Select "Image" from the tool bar; 2) Select "Resize" from the drop-down choices; 3) Set the DPI to 300 - 350 and change the pixel dimension to within the accepted range of 250 X 944; 4) If the new image file looks acceptable to you in the new dimensions, save the image file, by selecting "File" from the tool bar and using the "Save As" feature to save the file as a JPG image. If the image is not clear, do not submit the image. Instead, seek the assistance of a graphic artist to create the properly-sized .jpg file
