No instructions about using the app

Not recommended for amateurs. Most times I am comfortable clicking around an app to see how it works but this one is not easily understood. After only ten minutes with it I am frustrated by the lack of any instructions. The other and far more serious major irritant is that it puts its own advertisement watermark on each picture with no advice how to remove it.

Almost there...

The only thing I really needed this app for it does not do… resize based on width, not height .. then ftp to a server. 50% there guys. ALmost looked like what I needed from the screenshot. I really hope that this is fixed soon or I will be requesting a refund. If it is fixed my review will be 4-5 star! I really want to love this app.
