Problem with g2image insert in different levels of the website tree

I am using g2image/tinymce/gallery2 in some php webapplications:

I succeeded to insert images in the tinymce text via the G2image/Gallery2 button in tinymce. The programs that maintain the websites are in the maintenanceapplic part of the tree. The websitepages are in contact, nieuws ...
Everything seems to work after I added a text and a picture, but there still is a problem. When I update the tinymce textes (with the picture inside), ---> After this action, the link to the pictures in the wesite is corrupted because there is one level skipped ---> the websiteonderhoud level is skipped! What am I doing wrong!

The tree-structure op my website application:
