Question:
Aslm alykm, sheik. Please tellme about the different images of people on the day of Qiyamaa. Ie they teach us that some people will come when they are like pigs other every short etc.
Answer:
All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad 
is His Slave and Messenger.
The texts state that people will be resurrected in the same form that they were born; Allaah says (what means): {[It will be said to them], “And you have certainly come to Us alone [i.e. individually] as We created you the first time.} [Quran 6:94] Besides, Ibn ‘Abbaas 
said: the Prophet delivered a speech and said: "O people, you will be resurrected (and assembled) to Allaah bare-footed, naked and uncircumcised." Then the Prophet recited the Verse: {As We began the first creation, We will repeat it. [That is] a promise binding upon Us. Indeed, We will do it.} [Quran 21:104] [Al-Bukhari and Muslim]
When the people of Paradise will enter Paradise and the people of Hellfire will enter Hellfire, their images and ages will change; they will be thirty or thirty-three years old. The Prophet said: “The people of Paradise will enter Paradise hairless, beardless and with kohl (collyrium) in their eyes, aged thirty or thirty-three years.” [Ahmad and At-Tirmithi - Al-Albaani said it is Hasan (good) in Takhreej Ahaadeeth Al-Mishkaah]
Another narration by At-Tabaraani and Ibn Abi Ad-Dunya has the following addition: “…They will be in the shape of Aadam - sixty cubits tall and seven cubits wide."
Another narration by At-Tirmithi, which Shaykh Al-Albaani classified as weak, reads: “Whoever of the people of Paradise dies, young or old, will be aged thirty in Paradise and will never grow older, and the same applies to the people of Hell.”
As regards the non-Muslims (disbelievers) and their huge bodies, a Hadeeth of the Prophet reads: “The molar tooth of an unbeliever is as large as Uhud (a mountain in Madeenah) and the thickness of his skin is equivalent to three days journey for a fast rider.” [Muslim]
Also, At-Tirmithi, reported the Hadeeth with the following wording: “The thickness of the skin of a disbeliever is 42 cubits, and his molar tooth is as large as Uhud and his sitting place (i.e. the place that he physically occupies when sitting) in Hellfire is like the distance between Makkah and Madeenah.”
As regards what you mentioned in the question that some people will come (on the Day of Judgment) in the images of pigs and some others will be very short, we have not come across anything like this in the many reliable books that we have at hand.
Allaah Knows best.
