Description of every page/module: Hi there,

We are currently using a built in shopify theme on our store and face 2 major issues.

1) our images are proffesional quality done inside a studio, when we upload them, for some reason they are losing quality. We have tried various file types, sizes etc and cannot make this work. We think the theme is compressing the files perhaps so this needs fixing.

2) when we upload multiple photos for a product, the images on the product page simply stack on on top of another on that page. We want the photos to appear as small thumbnails and be selectable under the main image on the product pages as per most other sites. We can share photos of this if required, but many sites use this, its just not built into our theme.
