Hi,
This seems to be an interesting idea, but I had a query that the images to be slideshown will be accessed from photo gallery or they need to be bundled with the application. What purpose this app is going to serve to user?
The requirements that you have mentioned, I have already got experience in that part. So, I can deliver you the high quality product on time.
If I get this project, I will try to provide you the build in every 3 days. So that the final product is more smooth and clean.
We can discuss the requirement in detail, if needed.
Thanks.
