## Background
CROSS REFERENCE TO RELATED APPLICATION
This application is a 35 U.S.C. §371 national stage application of PCT International Application No. PCT/IB2013/060741, filed on 9 Dec. 2013, the disclosure and content of which is incorporated by reference herein in its entirety.
TECHNICAL FIELD
Embodiments herein relate to methods in an electronic mobile device for sending a picture over a wireless communications network to an electronic device. Other embodiments herein relate to an electronic mobile device.
BACKGROUND
The performance of cameras are growing in speed and quality, and more and more people are using cameras of their mobile electronic devices as main and only camera for all occasions. However, with high quality come the drawbacks of the size of the pictures taken.
As an example, five pictures taken with a mobile phone camera unit may occupy as much as 10 MB. Thus, when sending pictures as attachments of that size, systems like e-mail systems may refuse to handle the attachments due to poor resources or temporary lack of space in the email accounts. This is becoming a real problem that needs to be addressed with alternative solutions.
Some applications allow a user to modify resolution and quality of a picture right after attaching it to an e-mail and before sending. Although solving the problem of large attachments being difficult for systems to handle, this do not really solve the problem. Once a low resolution picture is selected, the receiver will receive a low resolution picture only, and there is nothing the receiver is able to do to influence the process. The same solution is present in a lot of applications and mobile electronic devices; the quality is selected before a picture is to be sent. If it is selected to take a photo with low quality due to concerns of file size to share over network, that low quality picture could never be enhanced since the quantity of pixels were lower when the picture was taken. Such a picture will never have a high resolution that maybe was wanted, but not chosen to use by the user due to such limitations.
Thus, there is a need of an alternative solution to the problem of sending pictures of high resolution quality occupying large resources in systems available for sending. Further, solutions of today limit a receiver to get what the sender decided.

BRIEF DESCRIPTION OF THE DRAWINGS
Examples of embodiments herein are described in more detail with reference to attached drawings in which:
FIG. 1 shows an electronic mobile device in accordance with embodiments herein.
FIG. 2 is a flow chart showing methods herein.



DETAILED DESCRIPTION
Embodiments herein will be exemplified in the following detailed non-limiting description.
FIG. 1 shows a system 10 in accordance with embodiments herein. The system 10 comprises an electronic mobile device 100, an electronic device 102 and a wireless communications network. The electronic mobile device 100 comprises a camera unit 104 adapted to capture a high resolution picture 105. The electronic mobile device 100 is adapted to send a picture to the electronic device 102 over the wireless communications network. The electronic mobile device 100 is adapted to create a low resolution picture 106 based on the high resolution picture 105, and is adapted to send the low resolution picture 106 to the electronic device 102, and, when a quality of resources in the wireless communications network is above a threshold, is adapted to send the high resolution picture 105 to at least one database 107 for storage. The database 107 may be comprised in a so called cloud. As an example, the cloud may be a computer network comprising one or more computers. A link to the high resolution picture 105 may be embedded in the low resolution picture 106.
With reference to FIG. 2, a method in the electronic mobile device 100 for sending a picture 105, 106 to an electronic device 102 will now be described.
Action 201
The electronic mobile device 100 captures a high resolution picture 105 with the camera unit 104.
Action 202
The electronic mobile device 100 creates a low resolution picture 106 based on the high resolution picture 105.
Action 203
The electronic mobile device 100 sends the low resolution picture 106 to the electronic device 102. Thereby, a user of the electronic device 102 receives a low quality picture, good enough to look at in a mobile device, pallet, tablet or the like, but still sent as a small attachment.
Action 204
When a quality of resources in the wireless communications network is above a threshold, the electronic mobile device 100 sends the high resolution picture 105 to the at least one database 107 for storage. Thus, traffic on the wireless communications network may be reduced since in some cases a larger file is kept on one server only.
Action 205
The electronic mobile device 100 may receive a request from a user of the electronic device 102 to send a high quality resolution picture.
Action 206
The electronic mobile device 100 may, when the quality of resources in the wireless communications network is above the threshold, send the high resolution picture 105 to the electronic device 102.
Action 206
The electronic mobile device 100 may, on request from the user of the electronic device 102, download the high resolution picture 105 from the at least one database 107 to the electronic device 102. The downloading action may be performed when the quality of resources in the wireless communications network is above the threshold. If a high resolution picture 105 is needed for example for printing purposes, it may be accessed for example via a menu to request back to a server a high resolution version of a picture.
