Help request


I'm not really sure whether I'm posting this in the right community. If not, feel free to delete, or to suggest where else I can possibly go.

I've got a problem with my journal concerning the layout. I wanted to change my header. I've already got one that was given to me and now I created a new one myself. Same format, about same size too, uploaded to photobucket, but the image doesn't show in the journal. It works with the other picture, so the html is correct. However, the new picture is simply not shown. Can anyone help me? Can you think of possible reasons why this happens, or what I can do to make it work? Help, please. Thanks in advance.
