put the right amount of images on one line

[jidanni@xxxxxxxxxxx]

Even with the hint 'width="125"', emacs-w3m just uses the width of the
word "staticmap" to guess how many of the images will fit on one line,
[staticmap] [staticmap] [staticmap] [staticmap] [staticmap] [staticmap]
[staticmap] [staticmap] [staticmap] [staticmap]
