Ladies and gentlemen, I call upon your artistic skill for something... I'm working on putting together a Windows Startup screen, and possibly, a different start screen for Maximus Arcade. For that, I would LOVE to get a great image of the 'turkey', from the pic below, and was hoping this might be an easy ask.

Here's my problem. Every image I've been able to find on the web is AWFUL. The turkey is small, the resolution is bad, and I really want to blow up the image to a size of (I'd say) 600px-900px square, so I could use it on pretty much any resolution, and as a full-screen image, if I ever wanted to. I believe (please correct me if I'm wrong) that a "vector image" of a picture would allow you to scale it infinitely, without any quality loss, but I don't know how to do that - and I'm pretty sure that the image provided (unless someone can find one better) doesn't really lend itself to a 'simple solution', by way of vectorizing it. (Is that even a word?)
My ask is this. Is it a simple/fairly simple task to get a fair size image of the turkey, with a transparent background, so that I can use it in my artwork? PNG is what I'm used to, but I can get access to Adobe Illustrator if the situation demands it. (Of course, I'd pretty much export it from the program to PNG anyway, as I'd need to to amalgamate it into my present work. (I really wish I had some skill in art, as I'd happily redraw the entire bird, but my turkey would likely come out looking horribly, horribly awful.)
Can anybody tell me my best course of action here? Thanks, in advance!
