For example: [login to view URL] In English, we need to store the page URL from: <img src="/shop/images/function/[login to view URL]"> to: <img src="/path_we_define/[login to view URL]"> In Chinese Page, we need to store the page URL from: <img src="/shop/images/function/[login to view URL]"> to: <img src="/path_we_define/[login to view URL]"> we only accept escrow payment. test on our server. if the code work, we simply release the money. this is super easy task, let me know if you need more information.
