At the time my file sold it was listed as "High" 3500 x 2343. That's where all the confusion started.
So here is how Steve explains what happened.
A couple other contributors also wanted to know why they didn't get reimbursed.
One of the issues was that the actual text stating the dimensions on the Photos.com page was wrong, while the image that the customer received was correct.
For instance, on the Photos.com page it would say something like this:
High (3500x2400)
In cases like this, the dimension text was wrong, but the actual deliverable was the correct smaller size. I went into Photos.com with a test account and confirmed this was the case.
When I downloaded the image the actual size was something more like 2400x1800.
If in your StockXpert balance sheet the line item said "L" then it was indeed an L size that got downloaded.
So thats the scoop! It was just a large sale after all.
