That is way to large of a picture if they are 2.11 MB. The gallery pictures should be in the lower KB range. Also remember that you are limited in the space you have in the gallery and even if you could get those in, you won't be able to put in many. Look at some of the pictures in other peoples galleries and see how large they are.
Edit to add: This is from my gallery and is just around 100 KB.
Edit: To remove picture.
