Gig Images size

[ashu244]

I have used 5000*3500 px for all of my gigs.
Should I need to change it?
Will it affect my gigs?

Mine are 1600x1076 but it should be fine although smaller size would make it load faster which is better UX.
I think they need to approve it when you change it but I’m not sure.
