You have failed to formulate a concise, clear and coherent question.

If you add the `img' or `object' element objects to the DOM tree yourself,
or provide a URI for the `src' or `data' attribute of the respective `img'
or `object' elements that does not refer an image resource at first, then
the corresponding images will not load before that takes place or you modify
the `src' or `data' attribute of those elements to refer to an image resource.

In any other way that is not possible, at least not interoperably, as
client-side DOM script support does not even have to be present, let alone
sufficiently enabled.

Thanks for the idea.
However if the URI points to a none image source, then the web page
will display a small red box, that doesn't look good.

You're welcome.

However if the URI points to a none image source, then the web page
will display a small red box,

In Microsoft Internet Explorer.

that doesn't look good.

True. So you could either set their `visiblity' style property to `hidden'
or their `display' style property to `none' at first. Or you would add the
`img' or `object' elements when they are needed. Be sure to provide a
no-script/no-DOM alternative in any case.
