If it ain't broken, don't fix it. If it's a little bit broken and nobody else notices, don't fix it either
The image has a "frame" it kind of fades into white along the edges. I only have a faint idea what I have done in Photoshop
It's not totally horrible but might look strange if it's printed on a page without cropping, "Why does the edges of this image look blurry???". But hey, they are downloading it, so I think I'll just forget about it
I didn't even notice this, but iStock inspectors sure did! "Remove the frame around the image!" - I was like "What the h*ll are they talking about", but they were right
