Weekly receive XML (containing book info like price, author's name, etc.) and IMAGE ( containing the bookcovers for the xml-based books) files from a publisher. However, sometimes, some books are assigned 'no image,' meaning that the related bookcovers were not available. As a result, we installed an image generator which supposed to automatically create custom bookcovers for any books assigned 'no image.' for any book with cover image. We want a freelancer who has a good knowledge of 'ONIX.' Please do not bid for this job if you have no working knowledge of xml files and online bookstore.
