Having a few issues when browsing 'Music Library > Albums' on PC and Android App:
1 - Album thumbnails are slow to load
2 - Occasionally thumbnails fail to load (timeout?) despite folder.jpg being present (and navigating into album always forces thumbnail to show correctly)
3 - Thumbnail is never show despite folder.jpg being present.
I believe all my issues are because the artwork is too high quality. Images in the hundreds of Kb are taking too long to load, and when I browse the complete album catalog, this can cause some to not show at all. My point 3. is because some of my images are over 1024x1024 pixels in size (although comment in below link refers to embedded content):
So my question and reason for this topic. What is the optimal artwork size for Sonos please? Are there any links to docs/specifications/wikis etc.? I resized some images to 200x200 pixels, which resulted in much faster loading, probably because they where now only ~25Kb in size.
I guessing Sonos s/w resizes artwork on the fly (I played with ImageMagick in a past life!)? Is there a size setting which would avoid resizing, for at least one of the browse catalogs, PC or App, for example?
