The bottm ones in your post Mindanao – Agusan del Sur show but not the others. Hmmm. I checked the properties of the blank space where your first image should be and the width is 448 in pixels. My experience has been that anything over 400 pixels in width will screw up the page and usually puts the sidebar at the bottom of the page. Maybe try resizing that first image to less than 400 pixels in width. Are all your images uploaded through the same place or by different servers?
I believe that Kodak Gallery doesn’t allow hotlinking. That having the images used on other sites. For example, I can’t even pull up your pictures when I put the picture’s URL into my browser’s URL bar.
Best bet would be to save them to your desktop and then upload them to your WP.com space following the FAQ.
