Hi, I've a similar issue, after saving an k2 item with an image on the image tab, I get the error:

0 imagejpeg(): Argument #3 ($quality) must be of type int, string given


Any ideas how to fix this?

0 imagecreatetruecolor(): Argument #1 ($width) must be of type int, string given

after a long time without an error message it appears again the error when uploading an image via K2 tab image.
In the meantime Joomle had updated itself as well as a few other tools. DEr Upload with JCE works
But there seems to be no solution for this or ?

I had the same problem. After searching for a long time, I found the solution. Check in the category, under the display settings, the values for "Options Image" to see if you've only entered numbers without the "px" at the end in the fields. After I switched to PHP 8, I also received an error message. After I removed the "px", it worked again.
