Hello again -
It seems that every time a page is called, whether an album page or individual images, the images see to be running through the coding each time. Google Pagespeed is installed on the server, which is supposed to cache things once they are initially called, to allow images and other items to load faster than running the code each time. However, for Koken, the images and thumbs load slowly, and display the three "loading dots" instead of immediately showing up. Is there a setting I am missing?
A key part of Koken involves image generation and caching. Koken creates images by using the image processing software installed on your web server. This process takes your uploaded images and generates smaller versions for use inside Koken and on your public web site. A variety of image sizes are generated for optimum load times across all screen sizes (phones, tablets, desktops, etc). Once smaller versions of images have been cached, those cached versions are re-used for optimum speed and performance. A cached copy of an image is only generated again if you replace its original file with a new version.
In all, Koken has the potential to create 28 different caches for each image you add to your library. That’s a lot of images, and more than most shared web hosts can handle being requested all at once. To workaround that limitation, Koken creates most cached images on-demand as needed to avoid overloading your web server. As the images are generated on demand (when the page is visited) it will take time until those images are created and cached again.
