Question Wishlist: Image resizer plugin in Kunena

Hi,

image sizes in modern smart phones grow every year. I try to motivate my users to live with the existing small image limit of 1240 x 1024 px . In my eyes enough for showing all necessary details.

However it means that users have to find solutions how to size down their existing images. I am aware how to raise the limit but my compressed backup is already 20 GB and main extension on my website is Kunena.

I would therefore appreciate a Kunena plugin that automatically scales down images when they are attached to a message. Hopefully I can motivate you with such a wish for future development.

You don't need an extra plugin for this. The images are reduced to the size you selected in the Kunena configuration when they are uploaded.
But this is the wrong way, as you will not achieve the desired result.
It is the png images that take up a lot of memory.
For example, I have the same image twice, one is a png and the other is a jpg.
The jpg has a size of 1920 x 1080 px and 486.5 kB
The png has a size of 800 x 450 px and 607.1 kB
As you can see, the png image is more than half smaller and still has more kB.
What you have to reduce in the configuration is Maximum Image File Size. The default setting for Kunena is 150 kB if it has not been changed. This prevents images that contain too much image information and are therefore too large from being uploaded. You can find this configuration in the Kunena configuration, tab Uploads.

Hi rich,

thanks for your reply. I have set the maximum image file size to 500 kB. It means that all images larger than that are refused. I have also set image max resolution to 1240 x 1024 px. And yes it can happen that png files of that size are refused. Sometimes even JPEG with too much details.

Do I understand you correctly that all images larger than 1240x1024 are automatically downscaled during upload (and not just during display). So if I enlarge max upload size to 1MB it will take a 2140 x 1820 image and scale it down using less space anyhow? So maximum image size is checked before it is downscaled? In that case I could increase the max file size limit to even 2 MB without too much harm and get rid of user nagging?

BTW: If you need support and test capabilities, drop me a note. I find your work awesome and am willing to give back some support.

It would put a strain on your site if several people did this at the same time, but in theory yes, the images should be scaled down. However, this does not work indefinitely, as the upload size is also limited by the server.

Thank you very much, we appreciate any support.
