I think the names of the files are just random titles assigned by the hosting site. (Though The RealTeeHill getting "Italian Art and Archaeology" from the second image is almost too interesting to just write off.)
The dimensions are a tad non-standard. First image is 1022x1024 (possibly a manual phone crop attempting a squarish shape). The second image is 1024x765. So even though I'm writing all this up, I'm also ruling out any significance by suggesting that the images were sized at n x 1024 then cropped.
I've tried tearing these images down in different ways and come to the conclusion that what is being shown here is pretty close to face value.
What I'm saying is, there doesn't seem to be any tricks. No hidden images. These are quite literally at least three small chests.
So now that I've set myself free of trying to find a hidden message embedded within the actual images themselves, I feel as lost as the first time I saw the pictures.
Besides the fact that the first had no wax, then the second two have wax... I think there may be something to get from the writing on the top of the two that (semi)clearly have script on top of them.
The script on top though, seems incomplete and unreadable (well, mostly unreadable) though I can make out some letters. I did a pretty lengthy comparison between the chests and the only other link in Trials Evolution; The Voynich Manuscript. I failed to see any similarity though, as they are different "languages."
