When you attaching an image to your pages using a FCK editor there’s a nice option to quicly edit the image (resize, crop, rotate, etc.) using build-in ImageEditor. However it doesn’t work from the beginning.
When you open it, at least in Evo 1.4 you see that the browser can’t load the picture itself.
This is because ImageEditor module uses relative path to the image. And since it is located under manager/media/ImageEditor it will never load images from assets/images/...
To fix it you can edit
manager/media/ImageEditor/editorFrame.php
Find the string:
<span id="imgCanvas" class="crop"><img src="<?php echo $imageInfo['src']; ?>"
And replace it with:
<span id="imgCanvas" class="crop"><img src="../../../<?php echo $imageInfo['src']; ?>"
Then you should be able to see your picture and edit it.
