You can enable/disable on a per-site basis, there is a switch in the popup panel to toggle for the current site.

When large media elements have been blocked on a page, you may force a reload of these elements interactively: if you hover over the placeholder of a blocked image and the cursor changes into a magnifier, this means that clicking on a blocked image will force a reload of that image.
|
||||
|
||||
If you use this feature and large media elements were blocked on a web page, the context menu will contain a new entry: _"Temporarily allow large media elements"_. When you click this entry, uBO will disable temporarily the blocking of large media element for the site, and attempt to load the blocked media elements without re-loading the page. In some cases you may need to force a reload of the page, for example if large media elements were fetched programmatically by the page. The temporary disabling will be removed for a tab as soon as you travel to a new site, or close the tab.

Note that this feature has no privacy value: a connection to the remote server must be performed in order to fetch the size of the resource. This of course applies only to resources which were not otherwise blocked by uBO's filtering engine.
