Improve profile picture quality and information

[Backtrennpapier]

Is your feature request related to a problem? Please describe.
Adding a photo of the user via the profile results in a highly downscaled picture, which is looking grainy in the profile page. I used high resolution pictures as original. I tried different pictures, square or rectangle, landing in 130px width or 170px height. This leads to confusion on my side where it is not clear what downscaling is done and how this relates to aspect ratios.

The current information text is not giving that clarity ("You should be in the photo yourself. The photo may have a maximum resolution of 44.74 MegaPixels. The photo file must not be larger than 44.74 MB and must be in JPG or PNG format.")

Describe the solution you'd like

• Increasing the resolution to at least 500px for the longest side of the image, 700px would be better
• Optimize information text and position on the "Edit my profile picture page"
  • Move instructions to above select a photo so they are first in the reading flow
  • Make it a bullet list to enhance readability
    • You should be in the photo yourself
    • The photo will be downscaled to 700px at the longest side
    • The photo's aspect ratio (landscape or portrait) will be retained
    • Allowed file types are PNG, JPG, JPEG
    • Allowed maximum file size is 44 MB {round down}
    • {Remove the megapixel statement, I assume it is too complex to understand for most users. if required, express in PX/DPI}
• If performance might be seen as a potential bottleneck, a thumbnail and/or multiple downsampled version of the original file should be generated
• Of course it would be perfect if this could be steered centrally, i.e. aspect ratio, and max resolution somewhere in the organizational preferences or a specific photo profile field setting, maybe later. The picture quality is the main improvement suggestion
