We have a small radio app of a page, which holds an ad in the middle column of the app, is taken from a web service, i don't know how but it was done by a developer, sorry i am not technical.
What we need :
An xml thing where we can put the image url and the website url/title, which will display it on the app and probably rotate ads every 30 seconds
(rotation was already done on the previous web service, i can show it when we chat)
Less than $30 job, if you want more, please pass on!
