If you need image instead of slider,then follow this steps :

Step 1: In your Shopify Admin go to online store > themes > customize.
step 2: Find slider and make it hidden by click on eye icon.

step 3: Then click on add section and find image banner.

step 4: In image banner choose image you want to show and then save.

Here your image is ready.
