What do you call "optimized and proper size"? I used to be able to load up pictures just fine last week, now I can't load any, just get the placeholder and the red X.
make sure your pictures are published to where they are supposed to be
if you have them in an images folder in your root directory then make sure that is where they are
i looked up where your source code is trying to find them and no pictures exist at those links so make sure of where they are and make sure the code matches or yes you will get a red x
as for size etc you can have a picture that appears to be 300x399 and actually bee 900x893 or something
I looked in the file manager and the files are there. When I click on the file they come up in a a new window. How big or small should the files be, I've been putting and pulling from the same place for the past month, It even worked earlier today, but now it doesn't.
So the picture is your background. Pictures don't just "go background", at some point you added this as your background. If you don't want this background, remove it. I don't know your "Printmaster 17", but just remove the part of your body tag that say:
BACKGROUND="img00000.jpg"
