No valid image was loaded

Hi,
I get this message 'no valid image loaded' whenever I try to save any editing, both in front end and back end, and regardless if an image was involved in the editing or not. CB 1.8, Joomla 2.5.4

I've read this topic . It says the issue is probably in a 3rd party plugin. Now I did not install any plugins myself. In the CB Plugin Manager I switched off all plugins except for these: Default, Default Language and CB Core. This makes no difference.

I hope someone can help me. I'm afraid I'm having much trouble with CB lately, while I really used to prefer it over other social community components for Joomla.

Kind regards, Frits

This turned out to be a conflict between CB and a plugin called Profile Picture, by Mosets. In fact I forgot that I installed this plugin, that's why it took me so long to figure out - and posted this topic.

So this topic is solved, and I promise I'll keep better track of my installs.
