5. The method of claim 4, wherein the predefined dimensions are such that the trimmed image has a width equal in size to its length.

6. The method of claim 1 further comprising:

storing the original image in a first directory;

determining whether a thumbnail image associated with the original image exists in a second directory;

generating a trimmed image from the original image if the thumbnail image fails to exist;

generating a thumbnail image from the trimmed image; and

storing the generated thumbnail image in the second directory.

7. The method of claim 6, wherein the second directory is a sub-directory of the first directory.

8. The method of claim 1, wherein the original image has a width X and a length Y, and wherein the trimmed image has a length smaller than Y, if Y is greater than X.

9. The method of claim 1, wherein the original image has a width X and a length Y, and wherein the trimmed image has a width smaller than X, if Y is smaller than X.

10. The method of claim 1, wherein the original image has a width X and a length Y, and m is a value greater than zero, wherein if mY<

(Y−

X) then upper border of the original image is trimmed by mY and lower border of original image is trimmed by mY−

X in order to produce the trimmed image.

11. The method of claim 1, wherein the original image has a width X and a length Y, and m is a value greater than zero, wherein if mY>

(Y−

X) then lower border of the original image is trimmed by Y−

X to produce the trimmed image.

12. The method of claim 10, wherein the value of m is between 0 and 1.

13. The method of claim 10, wherein the value of m is approximately 0.05.

14. The method of claim 11, wherein the value of m is between 0 and 1.

15. The method of claim 11, wherein the value of m is approximately 0.05.

16. The method of claim 1, wherein the original image has a width X and a length Y, and m is a value greater than zero, wherein if X>

Y then side borders of the original image are trimmed by m(X−

Y) each to produce the trimmed image.

17. The method of claim 16, wherein m is a value between 0 and 1.

18. The method of claim 16, wherein m is approximately 0.5.

19. The method of claim 1, wherein the original image has a width X and a length Y, wherein if X=Y then borders of the original image are not trimmed.

20. A method of viewing images accessible by a limited processing and limited display device, the method comprising:

generating a trimmed image from an original image accessible by the limited processing and limited display device, wherein the trimmed image'"'"'s dimension are relatively smaller or equal to the dimensions of the original image;

generating a thumbnail image from the trimmed image, such that dimensions of the thumbnail image are relatively smaller and directly proportional to the respective dimensions of the trimmed image, prior to receiving a request for displaying the thumbnail image on a screen of the limited processing and limited display device;

associating the thumbnail image with the original image so that in response to selection of the thumbnail image, the original image is displayed on the limited processing and limited display device; and

associating the thumbnail image with the original image so that any file management operations performed on the thumbnail image are also performed on the original image,

wherein the any file management operations comprise a move operation that allows both the original image and the thumbnail image to be transferred when either the original image or the thumbnail image is transferred, and an erase operation that allows both the original image and the thumbnail image to be deleted when either the original image or the thumbnail image is deleted.

21. The method of claim 20 further comprising:

storing the trimmed image on a storage medium readily accessible by the limited processing and limited display device.

22. The method of claim 20 wherein the trimmed image is trimmed on its borders based on the orientation of the original image.

23. The method of claim 20, wherein the trimmed image is trimmed along its height, if the original image has a width X smaller than a height Y.

24. The method of claim 23, wherein the trimmed image is trimmed along its height according to the following relationship:

if mY>

(Y−

X), then lower border of the original image is trimmed by Y−

X to produce the trimmed image;

wherein 0<

m<

1.

25. The method of claim 23, wherein the trimmed image is trimmed along its height according to the following relationship:

if mY<

(Y−

X), then upper border of the original image is trimmed by mY and lower border of original image is trimmed by mY−

X in order to produce the trimmed image, wherein 0<

m <

1.

26. The method of claim 20, wherein the trimmed image is trimmed along its width, if the original image has a width X longer than a height Y.

27. The method of claim 26, wherein the trimmed image is trimmed along its width by m(X−

Y) at its right and left border, wherein 0<

m<

1.

28. The method of claim 20, wherein the thumbnail image has predetermined fixed dimensions.

29. The method of claim 20, wherein the original image has dimensions X and Y, respectively associated with the width and height of the original image, and the trimmed image has dimension X1 and Y1, respectively associated with the width and height of the trimmed image, such that if X>

Y then X1 and Y1 are trimmed so that X1=Y and Y1=Y.

30. The method of claim 20, wherein the original image has dimensions X and Y, respectively associated with the width and height of the original image, and the trimmed image has dimension X1 and Y1, respectively associated with the width and height of the trimmed image, such that if X<

Y then X1 and Y1 are trimmed so that X1=X and Y1=X.

31. A method for displaying images on a display of a mobile device, the method comprising:
