Thank you for your post.
In your opening comments you said:
I see the icon in the Editor and the server searches for me - that’s easy, but it finds no images - I tried it with all paths - but nothing happened.
1.) I imagine that you have enabled the Joomla 'Simple image Gallery' plugin by JoomlaWorks?
2.) If so can you tell me your (1.) Joomla! version (2.) Server type (3.) Editor version (4.) JCK Manager version (4.) Browsers type & Version?
3.) Can you show me a few screen-shots of the problem, especially when the images don’t appear in the file browsers?
4.) Also it would be very helpful if we could get an error report. Would it be possible for you to install Firebug (which is a 3rd party extensions for Firefox - addons.mozilla.org/en-US/firefox/addon/1843/
). Once installed would you open up Firebug > select the ‘Console’ Tab, visit the page where the error is located and copy and paste the ‘query’ where you received the error.
