I’m a little confused about what you mean by GAE and how that might be different from the PHP backend. I’m getting a sense that you mean something specific here but are using the terms in a different way than is usually used, which is making it hard to answer your question. I also wonder if you are making this harder than it needs to be. A typical approach that people use for uploading data is to simply expose a HTTP endpoint that the mobile application can POST to with the image data (perhaps as multipart form data) and then if they need to return some sort of handle or metadata they simply do that in the response. It’s only one round-trip then. If you are running PHP on Google App Engine, the handler for that HTTP endpoint can then put the data wherever. I would suggest storing it in Google Cloud Storage and, if helpful, storing some meta-data about the data in the Datastore. > as you can notice this scenario will cost me a lot of time and the quality > of the image will be dropped due to encoding and decoding . > > > > I’m a little confused about the concern over image quality. Base64 encoding does not impact image quality - it is simply an encoding of binary data and is lossless (http://en.wikipedia.org/wiki/Base64). I hope this helps - again, it’s a little hard to understand your question or concerns. If I could suggest, it might help if you spend a little more time with the App Engine documentation. That might help you answer your own questions and it will likely help you ask questions using the terminology from the documentation, making it easier for others to help you.
