The image widget internally uses the "qx.util.ResourceManager" when it
sets the image source. The ResourceManager however only manages the
images which are "known" by qooxdoo (located inside the "resource"
folder(s) ). So if an image is not present (= the ResourceManager does
not manage it) the image widget uses the "qx.io2.ImageLoader" class to
load the image and shows the warning you mentioned (happens only once
per image in the source version).

Yes, because you are accessing a managed resource.

The mechanism of resource management was changed with 0.8. Only
resources managed by the framework can be used without warnings. This
has technical reasons.
To solve your problem you can either
add the images you need to your resources
or
use a "qx.ui.embed.Html" widget and embed the image as HTML.
I hope this answers your question. Maybe the documentation
http://qooxdoo.org/documentation/0.8/ui_resources
could also help.
cheers,
Alex
