Our client needs an app that is capable of extracting and parseing files names and generating a thumbnail gallery. The gallery will be placed on- and used as an overview to- a series of weekly changing adverts. Each thumbnail must also have a link to the respective advert. The files are hosted on a seperate server. Don't hesitate to contact us if you need us to be more specific. You should understand how ebay API, the Authentication token of ebay and how ebay sandbox works. Looking forward to hearing from you!
