I tried One Drive, too (it comes free with my email account) but I couldn't work it out. When you click on a particular photo, in the upper right corner there is a command "embed". Clicking on it, new window pops up, called "embed photo in a blog or web page" and it generates HTML code. Technically, copying and pasting this code should embed your photo in WH post, but the code is strange, my example:
<iframe src="https://onedrive.live.com/embed?cid=462F8E1F5A00AC21&resid=462F8E1F5A00AC21%21193&authkey=ACaIWCDAuu90ivc" width="320" height="240" frameborder="0" scrolling="no"></iframe>
After removing all the frame, width etc rubbish, I'm left with:
https://onedrive.live.com/embed?cid=462 ... CDAuu90ivcwhich will display the photo when I click on the link (this one should be an image of Easter cake
) but it does not want to work as embedded picture
maybe someone can take this further, I'm not great with all that computer stuff!
With Picasa it's so much easier. Once photos are uploaded to the album, right-click on your chosen picture and choose "copy image location". Then return to WH and simply paste the code:

Highlight the code and click IMG button:

Without the asterisks it embeds nicely:
Hope this helps...
I don't use flickr but I imagine the embedding procedure will be similar there?
