Hi,
Just to answer two of your questions.
You can view thumbnails in the files page by clicking on grid instead
of list at the top left corner of the screen.
I have copied a few of your images from the files section to pages.
You do this by clicking on edit then the top left icon is add image.
Choose your image toimport into the page. You can also write text in
there as well.
Hope this helps.
