The thumbnails cannot always be seen by Android users. The viewer can take forever to load pics some days, or close the page fully when you exit it, (loosing any text you may have started, etc.)
Basically, trying to use them is unpredictable for me. BUT as you load pictures, just before you hit finish, a small check box appears "insert full size". Check that and it will appear full sized wherever you last had the cursor. If you forget, there is an insert tool in blue at the bottom of each photos thumbnail box(here you can choose small, medium, or insert full size)
I.e. I'll answer again later but just lost a few paragraphs (twice 
) . I need a frustration break 
....and still have not seen the photos, lol 
Could you repost or edit? (under "take action")
