Post with two images on homepage

Since last week I'm unable to add images to my post as I used to do. Instead of one image on the homepage and a larger one in the post itself, two images appear on the homepage and one of them (the larger one) appears on the post itself. Unfortunately also without the text added to the image. I can't find the solution myself. Hopefully you can help me somehow! Would be great. M Mommers http://www.langeveldnatuurinbeeld.nl/
