4. The method in claim 1 , where the presenting the at least one marker-arrangement further comprises:

providing a first longitudinal line substantially fixed to the image recording arrangement to indicate a substantially fixed angle with respect to the recording arrangement, and

5. The method in claim 1 where the presenting the at least one marker-arrangement further comprises:

providing a first crosshair, substantially fixed to the image recording arrangement, to indicate a substantially fixed angle with respect to the recording arrangement, and

providing a second crosshair, substantially fixed to the horizon, to indicate a substantially fixed angle with respect to the horizon.

6. The method in claim 1 , where a size of the tilt angle is inversely proportional to a size of the first portion of the image.

maximizing the frame within the image.

8. The method in claim 1 further comprising:

cropping a second portion of the image, which is not enclosed by the frame.

9. The method in claim 1 , further comprising:

capturing the image with the image recording arrangement; and

storing, in the memory, the captured image together with information corresponding to the tilt-angle.

where the at least one marker-arrangement:

includes a frame overlaid on a first portion of the image,

has a substantially same shape as the image,

corresponds to a horizon, and

indicates a substantially fixed angle with respect to the horizon, and

where the aligning-unit is further to:

operatively select an aligned subset of the image, where the subset of the image is enclosed within the frame, and

store, in a memory associated with the portable imaging device, the aligned subset of the image.

11. The portable imaging device in claim 10 , where the tilt-sensor comprises one of a gyroscope arrangement or an accelerometer arrangement.

12. The portable imaging device in claim 10 , where the at least one marker-arrangement further comprises:

a first transversal line, substantially fixed to the image recording arrangement, so as to display a substantially fixed angle with respect to the image recording arrangement; and

a second transversal line, substantially fixed to the horizon, so as to display a substantially fixed angle with respect to the horizon.

13. The portable imaging device in claim 10 , where the at least one marker-arrangement further comprises:

a first longitudinal line substantially fixed to the image recording arrangement so as to display a substantially fixed angle with respect to the recording arrangement; and

a second longitudinal line substantially fixed to the horizon so as to display a substantially fixed angle with respect to the horizon.

14. The portable imaging device in claim 10 , where the at least one marker-arrangement further comprises:

a first crosshair substantially fixed to the image recording arrangement so as to display a substantially fixed angle with respect to the image recording arrangement, and

a second crosshair substantially fixed to the horizon so as to display a substantially fixed angle with respect to the horizon.

15. The portable imaging device in claim 10 , where a size of the tilt angle is inversely proportional to a size of the portion of the image.

16. The portable imaging device in claim 10 , where the aligning-unit operatively maximizes the frame within the image.

17. The portable device in claim 10 , where the aligning-unit operatively crops a second portion of the image, which is not enclosed by the frame.

18. The portable device in claim 10 , where the aligning-unit operatively stores the image together with information corresponding to the tilt-angle at which the image was recorded.

19. A computer program product stored on a computer usable medium, including readable program means for causing a portable device to execute when the program means is loaded in the portable device, the computer program product causing the portable device to:

record an image using an image recording arrangement of the portable device,

sense a tilt angle, using a tilt-sensor of the portable device, for the image recording arrangement,

present, via a display arrangement of the portable device, for presenting the image recorded by the image recording arrangement,

detect a tilt-angle for the image recording arrangement using the tilt sensor;

present at least one marker-arrangement via the display arrangement, indicative of the tilt-angle, where the at least one marker-arrangement:

includes a frame overlaid on a portion of the image,

has a substantially same shape as the image,

corresponds to a horizon, and

indicates a substantially fixed angle with respect to the horizon
