This may be an issue on the browser side. OmniOutliner will use whatever data the application you copied from puts on the clipboard - it doesn't convert the data format.

Example: I pointed my copy of Safari 5.1.2 at the Wikipedia logo image from their front page - use this link to point at the same image.

I copied the logo (which is in PNG format) to the clipboard, then opened OmniOutliner and pasted the image into a new document. Saving the document, then control-clicking on the file and selecting "Show Package Content" from the menu that appears shows that the file was saved with the image still in the original format. (See screenshot.)

Michaela, if you're seeing something else, please send details to our support ninjas and we'll be happy to investigate what's going on here. It's possible there's some edge case where something else happens, but the intent is for the app to do what you're requesting. Sorry for the trouble!
