Affiliate Marketing Secrets

My name is Tyler and I had a YouTube channel it got taken down on my third strike because of affiliate links AKA adfly. I mad a new channel called PigPuncherFTW i have an intro and all the equipment like green-screens mics etc but i am not talented with things like Photoshop or any type of photo editing. I need a YouTube background for my channel it needs to have a cartoon aspect to it but its mostly about games like COD,Minecraft etc. I will be able to pay you if you send me a address or something but i need to at least see the background first money is not the problem for me and you would have to trust me.

I’m working on the beginnings of a few websites for some organizations I am affiliated with, and I had this thought: I know the traditional view is that screens project at 72/96ppi, but I know this is not the case as a computer screen goes by the actual pixels and not dpi/ppi (a 357px by 423px image will display that many pixels regardless of monitor resolution…it will just look “bigger” or “smaller” depending on the resolution). So my question is, as I’m designing my site(s), does it really matter what resolution I design at? 300 so I can see more detail? Any clarification will certainly help! Thanks in advance!
