Mylio is a dream tool for carrying huge photo libraries on mobile devices and people mostly can’t believe that it is possible to have so many well organized and well presented photos in your pocket or bag.
Memory on mobile devices is always scarce.
Syncing only Thumbnails to mobile devices in order to save memory is a bad idea, as the Thumbnails are super small (213x320 pixel) so that viewing an image on the full screen is near to impossible.
Syncing previews, however, is often impossible because the file size of the current Mylio Preview jpgs is too big for the available memory.
So my feature request is to create a new preview class for mobile devices with a lower quality, which take up less memory but are optically sufficient for viewing images full screen.
I can give you some more background info for my feature request:
My Mylio library is 125.000 photos.
The Device Quality shows the space needed for Thumbnails with 2.2 GB, for Originals with 1.49TB.
I have looked at about 2 dozens of Preview-jpgs in the Mylio Generated Image Bundle: image size is about 1365x2048 pixel, the file size varies between 250KB and 800KB.
The image size of Thumbnails is only 213x320 pixels with a file size between 24-35KB.
On my MacMini I have set the Device Quality to sync all previews and no originals - the size of the Library on Disk is 83.5 GB - which in my opinion would be far too big for a mobile device (in fact, my beloved big iPad Pro does not have sufficient free space for previews any more).
With NO Previews and NO Originals synced, the Library takes up 36 GB on my iPadPro 12.9" and 39GB on my mobile phone Huawei P20+.
The iPadPro 12.9" has a screen size of 2048x2732 pixel, the Huawei 1080x2240. Most current middle and top class mobiles have screen resolutions in and above this range.
People always keep huge numbers of Originals for long time on their mobiles ( and even Mylio users don’t regularly replace the Originals by smaller Mylio previews or Thumbnails). So memory on a mobile is always scarce.
I experimented a bit with the jpg quality settings of a Mylio Preview jpg.
The photo I have chosen shows a look into the inside of an architectural model of the Elb-Philharmonie in Hamburg with lots of details.
Here is the Mylio Preview jpg as found in the Generated Image Bundle with a file size of 799KB
Next is the same jpg saved at only 50% quality setting, which keeps the image size but reduces the file size to 323KB:
Last it is saved at 15% quality setting, bringing the file size down to 188KB:
Of course there is a visible loss in quality, but even at the low 15% quality setting this is a photo that gives you a sufficient idea of the original quality and which you can use for showing to other people. What is not possible with the Thumbnail:
I hope this feature request finds your support and can be realized by Mylio’s wonderful Development Team (Thank you guys for your work!)
