Fix issue on my shopify page ASAP

Fix template issues on my Shopify page:

- Some images are overlapping text and other images (Shopify Support said it is a third-party template issue)
- The collection icon is showing a white background and it should be clear (PNG photos)
- Test page for speed and functionality

****Note: I would like a quote to put a button (flag) above the navigation bar to change the language of the shop****

I need the work completed as soon as possible
