Hello!
i've got a problem, whenever I create an article and I do not upload an image, K2 autoasignes one. Well It didn't use to happen. What can I do? I'd rather have my articles without any images I don't upload. Or I'd prefer the Joomla's image by default but not random images. Please help me out!

Thank you!
:S

check the k2 dashboard paramaters image tab, there is a setting there to control this behavior

I also have this problem. I do not find the sloution in the K2 image parameters. Is this a K2 problem or a template-problem? Did you find the solution?

Is it appearing in the front end or in the adminstrator area as well?

If it is in the front end then this is a template issue. If it is in the backend then a plugin is generating that image.
