To minimize size of the manjaro package and to provide the best experience for our users, we follow these optmization steps for each image:

• You'll need these packages for the tools used here:
  imagemagick, jhead and mozjpeg

• Convert image to JPG if in another format if is a photo, we can accept PNG format if the size is not huge:
  mogrify -format jpg <imagefile>

• Scale down image to match 4K (3840x2400) size:
  mogrify -resize 3840x <image.jpg>

• If image is still huge in size (above 4MB), check it's quality level:
  identify -verbose <image.jpg> | grep 'Image:\|Quality'
  If higher than 92, reduce it down:
  mogrify -quality 92 <image.jpg>

• Remove all metadata except XMP and comments:
  jhead -autorot -de -di -du -c <image.jpg>

• Losslessly optimize images with mozjpeg:
  /opt/mozjpeg/bin/jpegtran -optimize -progressive -outfile 'Output.jpg' 'Input.jpg'

After renaming the resulting image to Image_Title_by_Artist format, it is ready for inclusion.
