Sorry I wasn't clearer in my explanation, I hope the visuals are more helpful!
STEP ONE:
So here, I've just checked the one picture, but if you want 10, 20, 30 thumbnails, then you can check that many in one go.
STEP TWO:
When you've gone and clicked on the Generate HTML and IMG code, it will present this page. I've gone and highlighted the code that's right for MH thumbnail. You just copy and paste it.
WOW! I LOVE those Deidi pics Sakura-Aniki!
Awesome. I hadn't seen any of those, so now my photobucket is a little bit fuller than it was before.
I esp. love the doujinshi pics. Beautiful.
And UchihaMadara1, you're right, that is a really good portrayal of an adult Naruto. Thanks for sharing...gonna watch that artist.
