The box with the X would indicate that the picture file was not successfully uploaded for some reason.
Exactly what the problem may be is difficult to tell. You will need to provide more detailed information.
One thing that could be the problem is where the pictures are stored.
Assuming that you're using an HTML editor program to write your page, and are using the "Insert" menu to insert the pictures into the page, what is the pathway to picture files? For instance, if your pictures are stored in:
C:\My Documents\My Pictures
and you insert the picture file, the pathway to image will be the same. When the picture file is uploaded, it will try to find the picture at an address like:
http://www.your_address/my%documents/my%pictures/image01.jpg(Note, there can't be any spaces, so a % sign will be placed in the space.)
Unless you've created those image folders on your Web server, the pictures will not be found, and thus won't show.
A simple way to deal with this is to put the pictures files into the same folder as your web page files. Then when you insert the picture, the pathway would be the same as the page.
As an example, go to this page:
http://www.alaska.net/~black/irfan.htmThen right click on one of the images and choose "properties". Note the pathway to the file.
http://www.alaska.net/~black/irfan.jpgThe picture is located in the "www" folder, the same as the page.
Right click on one of the boxes with the red X and see what the address for the picture is. Is that where the picture file was uploaded too? If not, upload the picture (or move it) to the correct address.
I hope this will help.
