The above screenshot was provided by Microgaming (I added the word "VOID" to protect others from fraud). This screenshot will give you an idea where lines should meet and what the spacing ought to be concerning the monkey and banana images on the reels.
Here is the screenshot that was sent to the casino (and to the OPA) and I've taken the liberty to highlight what I think is odd. Anyone who does any work in Photoshop would be able to pick this out. The jpg that the player provided was taken by a digital camera, but in my opinion the player (or someone this person knows) created this image and then took a snapshot. You be the judge.
