There's no BBCode to manually resize images, but there are different image URLs you can use for dragons in particular! For other tips and tricks, I suggest
Crowe's BBCode Compendium, but I'll be using your Vividleaf as an example for dragon images.
This is the standard dragon image, and we the image URL from "Generate Code" (with the link tags removed). You can also get this code by right-clicking the dragon, selecting "Copy Image Address," and deleting everything after ".png" in the URL. This is because an image link must end in the proper file extension (.png, .jpeg, and so on) in order to work properly.
Code:
http://flightrising.com/rendern/350/419721/41972070_350.png
Notice that instead of just the dragon's ID number, there are
two numbers identifying the dragon, right between the "350"s. Vividleaf's numbers are
419721/41972070. If you want to post a different dragon's picture, copy their ID numbers and replace Vividleaf's numbers with the new ones.
This is the thumbnail code, which is the small image seen from your lair, and likely the one you were asking for. You can get this code for any dragon by doing the same right-click/Copy Image Address/delete everything after the ".png" as I mentioned before...but, you can still just replace Vividleaf's numbers here with the other dragon's ID numbers.
Code:

Note that all of these images will update to match if the dragon is gened, breedchanged, or dressed up. If you want them to keep a specific look, for whatever reason, you'd have to save the image as it is and re-upload it elsewhere.
Now for a little extra fun; you can also make the avatars and Coliseum portraits show up in the forums!
First, avatars. Same principle as the others; copy the dragon's ID numbers into the following code, which you can obtain by right-clicking on any user's icon, including in your "change avatar" window. Be sure to leave the "p" where it is, though, or the image will break!

Lastly, Coliseum portraits! These are the little banners that display your dragons when fighting in the Coliseum. I'm actually not sure how this code was initially discovered, but it works for any adult dragon. I hope this post was helpful!
