Abstract

The present invention relates to transmitting an image using a mobile terminal. The present invention comprises selecting at least one image having a predetermined resolution, checking a first size of the at least one image, determining whether the first size of the at least one image exceeds a transmittable size, adjusting the predetermined resolution of at least one of the at least one image if the first size exceeds the transmittable size, wherein the predetermined resolution is adjusted so that a second size of the at least one image does not exceed the transmittable size, and transmitting that at least one image having the second size.

means for transmitting the at least one image having the second size.

15. The mobile communication device of claim 14, further comprising means for transmitting an unadjusted image with the at least one image having the second size.

16. The mobile communication device of claim 14, further comprising:

means for attaching the at least one image to a message if the second size of the at least one image does not exceed the transmittable size; and
