Not sure what you mean by "
Do I have to put each picture into coffeecup or can I put it in, in the folder?" If I understand correctly, you are asking about dragging the image folder from where it is stored on your machine to the 'resource browser' along the left side of the HTML Editor?
Do it like this: place the folder 'newsite' that I sent you next to your original web folder (assuming you may have called it 'oldsite') Then open the Editor and browse to the 'newsite' folder so that you have it open. Then all the files and subfolders will appear along the left side. When editing a page, open it from the 'newsite'. When creating new sites, save them to the same folder. When inserting an image, you click on the image icon in the Editor and browse until you have found the images folder inside 'newsite', then pick the image you want. If I were you, I would also add images you
plan to use to that image folder (after you have made them the right size). Then the linking should be a breeze.
The broken image icon and the outline mean that the image is not in the right place on your server, or the path to it in the html file is not correct. That seems to have been one of your problems all along. On the page 'reviews' where you have made changes, it's the paths to the images in the html file that are wrong. Read again what I wrote above in my previous reply to you. But it should be easier if you place images in the 'images' folder before you start linking to them.
