I'm trying to change an image on my landing page so I went into visual studio code and changed the image from this:

To this:

Yet when I reload the landing page it still shows hand_pp not visa_pp.
I'm sure it's something simple I'm missing so any advice would be greatly appreciated

If you did reupload, are you still using Amazon S3 with CloudFront?
If so, this is due to CloudFront cache. See here:
