Revision history [back]

It seems I found the answer!)
In Firefox browser I pressed ctrl+U to get html code of sage worksheet web page. Then I pressed ctrl+F (the search) and typed "img" (without quotes). I found that image (logo of sage at left top corner of sage worksheet) is sagenb.png. After that in terminal:

locate sagenb.png

The result for me from locate function is:
/home/andrei/sage-5.10/devel/sagenb-main/sagenb/data/sage/images/sagenb.png
So this image folder is that place where I can store my image files.
