Images sent with "Send image" are scaled up, if their short sides are less than 1600 Pixels

[MoonlightWave-12]

Bug Description

If one sends an image that has a resolution of, for example, 800x600, with "Send Image", the image will be scaled up to 1600x1200. This increases the file-size, without improving the quality.

Steps to Reproduce

1. Open a chat.
2. Select the + in the text-input-area.
3. Choose "Send image".
4. Make sure that "Send original" is off.
5. Choose an image which is shorter than 1600 pixels on the long sides.
6. Download the sent image and check the resolution of the image.

Expected Behavior

The resolution of the image should be the same as the resolution of the original image (but not longer than 1600 pixels on the long sides).
