It's hard to tell with all the glare and condensation, but this doesn't really look like an infection to me. It might just be yeast rafts, CO2 bubbles, residual Starsan foam, or a combination of all.
I say leave it be for a week or two. If it's got one of the more common beer-infecting bacteria (lactobacillus or pediococcus) it will develop a very noticeable bubbly white "skin", also known as a pellicle. If it doesn't worsen noticeably, give it a taste. If it tastes fine and the gravity is stable, it's probably fine. If it tastes off or looks noticeably worse, you've still got some options before you decide to dump it, but whatever you do, DO NOT bottle it if the gravity is not stable.
