That sounds close to what I'm after.  How can I access RTE 
configurations, like the Checkbox "Source Code"?
There are hundreds of images that need to be inserted into various 
content elements.  I don't want to insert images manually in the 
backend.  So I wrote a Perl script to insert images into the tt_content 
table directly.  Then I noticed that only inserting image link in the 
image_link field did not show the image at all.  Sorry if this bit more 
background information came so late.

The images have already been uploaded into the subdirectories within 
fileadmin.

Anyway, thanks much for all your help.
