During a recent review of my clients error logs I spotted an unusual entry for a bunch of images which didn’t exist within the file system. I knew the website well and knew the missing images shouldn’t be there which lead me to question what were they being called for?
File does not exist: /var/www/public_html/apple-touch-icon-72x72-precomposed.png File does not exist: /var/www/public_html/apple-touch-icon-72x72.png File does not exist: /var/www/public_html/apple-touch-icon-precomposed.png
As I’ve previously written Regular Error Log Review can provide an expectational insight into a websites activity and this is a fine example.
The name of the images gave the biggest clue and after reading some documents it appears Apple expect website owners to host thumbnail or icon images so the iPhone, iPad or iSomething can use the image for its graphical interface.
If an iPhone user saves a website on their homepage it will look for an associated image hosted on the website to use as an icon. Obviously the website had been added many times on Apple devices and the IOS was looking for the images which caused the errors.
Once I designed and uploaded the appropriate images in all their formats and names the errors stopped and the Apple users had their new icons which provided further value to my clients website and its user experience.
