Sorry if this question has been asked before I did a quick skim and couldn’t find anything.

I’m trying to add a banner and background image to my profile but every time I try it says upload failed I do t know if it’s a problem on my end or if there’s specific requirements I have to follow for background and banner images.

Thank You.

edit: I’m pretty sure it was just a problem on my end because it works now and thank you to everyone who answered 

I think there's a three megabyte limit.

Far as I can tell, I think screenshots have to be below 3mb and below something like 2160x2160 resolution.

As for thumbnails, I’m not sure, but I tend to go with a resolution of 630x500 for mine.
