Topic: Slow to load, plus stutter on iPhone 4S and iPad

Hi,

I've noticed that sometimes images stutter or are sometimes VERY slow to load. Other times the images load quickly and don't stutter. The behavior is unpredictable. Happens on both my iPhone 4S and my original iPad.

Some info to help troubleshoot:

  • Juicebox version 1.1.1, latest.

  • Gallery URL: http://hatefyamini.com/photos/northwest/

  • My images galleries are exported via LR4 and images tend to be about 700KB.

  • iPhone 4S running iOS 5.1

  • iPad running iOS 5.1

  • My wifi connection speed is about 5Mbps

Viewing galleries on the desktop does not present any stutter.

Any advice would be very much appreciated. Thank you!

Re: Slow to load, plus stutter on iPhone 4S and iPad

I would recommend reducing the filesize of your images. The dimensions are OK (approximately 1024 x 768) but you could reduce the quality setting ('Output Settings -> JPG Quality') to bring the filesize down to somewhere between 100KB and 200KB.
As an example of a reasonable compromise between size and quality, the default settings of JuiceboxBuilder-Pro resize my original 4416 x 3312 10MB files into 1024 x 768 files of approximately 85KB each which are suitable for web gallery use.
Juicebox will then be able to load your images significantly quicker.

You may also like to change the imagePreloading option which determines how images are preloaded. Possible values for this options are PAGE, NEXT, ALL and NONE.
