convert images at the remote appVm to make them secure then downalod them to dom0 then convert it 2 time the same way
Store it at dom0 then chmod +x it then
`qvm-wallpaper-tool {path_to_jpg_or_png}
- Convert image at AppVM with ImageMagick and store it with new temp name at AppVM
- Download converted image to dom0 temp
- Convert it 2(next) time at dom0 to prevent maybe possible injections at AppVM
- No without GUI
- It's only works with jpg and png filenames at remote AppVM (for securety reasons)
- It do not set wallpapers. Only store them at user Pics directory (do not know how to set wallpapers, I tied some code and it does not work)
