The working

Pixels are inches multiplied by the resolution, and an inch is 25.4 mm.

Width: 105 mm ÷ 25.4 = 4.134 in; 4.134 in × 600 = 2,480.3, which rounds to 2480 pixels.
Height: 148 mm ÷ 25.4 = 5.827 in; 5.827 in × 600 = 3,496.1, which rounds to 3496 pixels.

Bleed is extra image past the trim line, so that a cut that lands slightly off still leaves ink to the edge. Print shops usually ask for 3 mm on every side of an A-series page, which makes the file 2622 × 3638 pixels.

Is your photo big enough?

To fill A6 at 600 DPI an image needs at least 2480 × 3496 pixels. Cropped to fill the sheet:

A 12 megapixel phone photo (4000 × 3000) gives 686 DPI: enough.
A 24 megapixel camera photo (6000 × 4000) gives 968 DPI: enough.
A 48 megapixel photo (8000 × 6000) gives 1,373 DPI: enough.

At 600 DPI the pixels of a print blend together from about 5.7 inches (15 cm) away. 600 DPI is used for line art, small text and scans that will be enlarged. It is also the native resolution of many office laser printers.
