Assuming, that my site is driven by Mediawiki, you could use Commons as a foreign file repository. You can embed all files from Commons like local files.

You may take a look here: Manual:$wgUseInstantCommons and there: Manual:$wgForeignFileRepos.

With such a configuration you type in your wikitext. And it will be rendered to your chosen size automatically.
