Description Bernhard Rosenkraenzer 2008-10-09 02:48:20 PDT 
Loading images from the local filesystem (file:/ URLs) fails in current snapshots if the HTML code has been set by QWebView::setHtml (e.g. HTML code generated on the fly by a local application) as opposed to having been loaded from a file:/ URL.

This is caused by current WebKit defaulting FrameLoader::localLoadPolicy to AllowLocalLoadsForLocalOnly (as opposed to AllowLocalLoadsForLocalAndSubstituteData), and the QtWebKit API not having the functionality to override this.

There should be a way to set FrameLoader::localLoadPolicy through the QtWebKit API (QWebSettings::globalSettings()->setAttribute(QWebSettings::allowLocalLoads); or something?).
For compatibility with some legacy applications, it may also make sense to have the option to set localLoadPolicy to AllowLocalLoadsForAll, the way it used to be in older WebKit versions.

ok this bug is solved changing in FrameLoader.cpp the code 

static FrameLoader::LocalLoadPolicy localLoadPolicy = FrameLoader::AllowLocalLoadsForLocalOnly for

static FrameLoader::LocalLoadPolicy localLoadPolicy = FrameLoader::AllowLocalLoadsForAll. 

But now, I can't to access an image provided by a AdServer. 
	
Are there any restrictions on access to external images?
