If that link doesn't work: "images" folder > "Add file" button > "Upload files"
- Upload any new images from this interface
- Click "commit changes"
- Wait for about a minute
- The new pictures should appear on the site
If something went wrong, it's almost certainly in the actions (automated processes that rebuild/deploy the site when new things are uploaded).
- check the symbols:
- yellow dots mean it's still processing
- red crosses mean something went wrong and you'll probably have to ask Ginger
- grey circles with exclamation marks mean it was skipped, which is probably fine
- green ticks are all good
- check the times on the right hand side:
- if the latest one doesn't match up with when you uploaded the files (roughly), it may not have started running for some reason
- wait until you upload something else, and if it doesn't work again then ask Ginger
