images does not display into the editor

I have all my images (not the images uploaded from the editor) into a folder called Images.

so lets say that I have a sun.jpg image into this folder.

in my aspx page I use <img src="../Images/sun.jpg" alt="" /> if the file is into another folder rather than the root .

The image display fine into the page, but when I load the page into the editor, i get the classic

X

for image not found. In order to work I need to add an extra ../ to the src.

but by doing this, the image display into the editor but not into the file.

Now rather than moving all the images into another folder, how can I solve this ?
