Hi!

i sell secondhand clothing and every time I upload photos with some kind of stripe pattern (from a light tone on tone ribbing to a contrasting stripe pattern) the photos show a crazy swirl and circle pattern once uploaded to Shopify.

the photos are fine before being uploaded.

i have tried compressing the images before uploading and it didn’t help.

this is preventing me from selling these products as the images look terrible.
