hey. sopme of the new animations keep telling me invalid source when I load the page. how do I fix this.

Do those new animations that return invalid sources happen to be webm? You need a compatible browser to play them.

Use an up-to-date webm-compatible browser.
Webm-compatible browsers include Google Chrome, Opera, and Firefox. Internet Explorer requires a third-party plugin.

You can also download them (right-click "Original Image" and select "Save Link as...") and play the file in a compatible media player like VLC.
