iPhone requirement for full screen contact picture incoming call

[freemannnn]

i am trying to make some contacts of mine to appear full screen when they call. (ios 8 gm with iphone 5)
i upload the pictures through icloud.com because its easier.
pictures that i have shot before with my previous iphone 3gs or 4.
the thing is that appears only a circle on the top right.
if i shot a picture and place it direct with the photos app everything is ok.
i also download some wallpapers from net with res 640x1136 place them in contact photo but when they ring the same small circle.
so what is "required" for a pic to show full screen?

Just re-add the picture for each contact, and they will now be full screen again.

I have experienced that the picture has to be some sort of minimum size/dimensions but have never seen any action minimum requirements. however when i added small thumbnails it was shown as small picture and when i added larger images i got full screen caller id
