Covers/ Thumbnails


Jun 16, 2017 03:19PM EDT

Hello! I am having a lot of difficulty assigning covers to albums in a tiered filesystem. I have read the referenced articles on how to do this, but it is not at all intuitive or cooperating with what I want. I use Chastain and cannot seem to get the pictures I want at the forefront of a collection or album.

Additionally, when I share a link to my site (i.e. on facebook) the thumbnail looks AWFUL. I have no idea how or why this happens, or even how to try switching it to a different photo. I wish I could attach a picture... but basically the photo is horribly pixelated and discolored.

Try it for yourself by trying to share
Please help! This reflects very poorly on my work.

Hello. Here’s how to Edit Album Covers

Regarding Pixelated images

To fix an individual pixilated image, find the pixilated images(s) via the web browser. Then log into Koken and find the exact image(s) in the Library. Rotate the image and then rotate it back. This will force the server to re-render that specific image and the pixelation is gone.

Long answer:
Let me try to explain what was happening. The issues you describe are due to your host’s resource limitations and may happen after a period of activity; the actual cause is on the hosting side.

Shared hosting accounts are exactly that; many websites share a server. Hosting companies place restrictions on the amount of server resources available to any one site to minimize the chance a resource intensive site will slow down every other site.

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.

Thanks for your response! Unfortunately I don't think I was clear enough in explaining my problem.

The issue is not on the koken site itself, it is an issue with the default thumbnail that represents the site. So when I post a link to the site on Facebook, the default image associated with my site is a horribly pixelated image. The same goes for other platforms where a preview is shown, sometimes when you hover over the link it shows an image associated with an article, etc.

I do not know how to select the site thumbnail, so I couldn't change it if I tried.
I tried rotating the image, as suggested, and to no avail. The thumbnail is still awful.

How can I fix/ change the default thumbnail associated with my site?
