You just need to upload the picture as you do usually (with original size)
1.Go to a photo you've already uploaded.
2.Click the link 'Make Profile Picture' below the photo.
3.Click 'Confirm'
then facebook gives you option to resize or crop the image.
.
Another quick way to upload a new profile picture is to use your post-by-email address and add '+ profile' before the '@' sign. (Example: abcdefg+profile@facebook.com).
