Karlie here from the Shopify Support Team! Can you tell me when this issue first occurred? Have you recently downloaded any apps or made any theme changes that could have resulted in the issue you're having with your images? What we can do is take this conversation to email so that I can escalate this issue up to our theme team for you - are you okay if I email the email address associated with your Shopify Forums account?
Looking forward to hearing back from you!
Karlie again! I've gone ahead and sent you an email. You should see it in your inbox for the email address attached to your Shopify Forums account. Be sure to reply back to that email so we can continue working on this issue together.
