Instead of letting the attachments appear at the bottom of the post as normal, use the "Insert Inline" button. You will get something like <ATTACH>41247</ATTACH> (but with square brackets). Then place the ### Latest WIP ### tag above the one you want to show in the scraper. To be sure you know which is which, you can check only one of the images and insert that, then check the other and insert it. That way, you can be sure they've shown up in the order that you intend.
