How to Take a Digital Photo for Online Visitors Visa Renewal?

[coinguy]

I'm not really sure how to measure the photo digitally so that it measures that way. I assume that is about the same size as a passport or PR photo but I really cannot be sure. I have everything else right and know that CIC would only grant a visitors visa online if this is precise. I would love some suggestions and feedback.

Here it is verbatim from the CIC website:

Dimensions:
• The final frame size of the photo must be at least 35 mm x 45 mm (1 3/8" x 1 ¾").
• The photographs must show the full front view of the head, with the face in the middle of the photograph, and include the top of the shoulders.
• The size of the head, from chin to crown, must be between 31 mm (1 ¼") and 36 mm (1 7/16").
• Digital dimensions are often expressed in pixels or DPI (dots per inch). The physical dimensions in pixels must be at least 420 x 540.
Quality/Resolution:
• If an existing photo is being scanned, the minimum resolution must be 600 pixels per inch.
File Format:
• The file may be submitted in JPEG or JPEG2000 format.
File Size:
• The final size of the image should be ideally 240 kB (kilobytes), but not less than 60 kB.
Colour:
• The image must be in color (24 bits per pixel) in sRGB colour space which is the common output for most digital cameras.

Submit the same picture as was sold to you, usually the guys who take the picture already know what they are doing.
