61711 - Backend support for loading images after page is loaded

Status: NEW

(Core :: Layout, enhancement)

Description

[timeless]

In order to implement a Show Images toolbar button, there needs to be a method 
that can be called to load document images.

I think the following values as a parameter should also be accepted
refetchImages
loadMissingImages
loadSiteImages [this does not include blocked images]
loadNonsiteImages [offsite images that are not blocked]
loadBlockedImages [this overrides the users preference not to load certain 
images]
loadImages=loadSiteImages+loadNonsiteImages
loadAllImages=loadMissingImages+loadImages
SuppressUserPrompt [there is a pref to ask the user before loading each image, 
this flag would override that preference]

Similarly, it would be helpful if there was a status to indicate if the page 
knows of any images that aren't loaded [and to which category they belong].

Reassigning to layout. The embedding people would quite like to see a more 
fine-grain method to enable image loading as well.

where do you want this "load document images" method?  what do you want the
result to be?  adam, what priority does this have for the embedding team?
thanks.

This is doable completely via chrome JS, no?  Grab the images from the DOM, QI
to nsIImageLoadingContent, kick off the loads.  Make sure that your content
policy impl doesn't block them.

So in my opinion this bug is mis-assigned.
