For the blog images, I simply click in the backoffice at the place where i want the image to go. And click on insert, after that i upload the image and insert it after clicking on save. The image can be seen then. Also, it is present in the blog backoffice in the HTML language, But when i publish it, the image is not there.
For the header, i dont know what the problem is. There is either a broken file image or a red cross at the top left side of the header bar.
