Ovi Share Redesigned - How To Change Embed Size

I wrote "Flickr vs Share on Ovi: Resizing Quality" in other times, and then Ovi's resizing quality was actually bad. Now Ovi Share has been totally redesigned. Photos uploaded before were also reprocessed and got the high quality as below.

Ovi offers only one embed size, which is small thumbnail size. It seems not convenient for us to embed in blogs. But we can use other sizes by changing embed code manually.
Embed Code Sample:
<a href="http://share.ovi.com/media/takeoka.public/takeoka.10088"><img src="http://media.share.ovi.com/m1/st/0141/address_to_image.jpg" border="0" title="Title" alt="Title" width="56" height="100" /></a>
See the underlined st. This means small thumbnail. You can change embed size by changing this part. Changing rule is as written below:
st - small thumbnail
lt - large thumbnail
s - small
m - medium
l - large
