so you'll have to use different attributes and classes to get at the thing. i used:

#flickr_badge_uber_wrapper {<br /> width:100% !important;<br /> border:0;<br /> }
to set the width (you can also use px, if you know the width of your sidebar)

<br /> #flickr_badge_uber_wrapper * {<br /> background:#ddd;<br /> display:inline;<br /> float:left;<br /> }
the asterisk means "everything inside of". that's how i get the images to wrap, instead of stacking vertically.
#flickr_badge_uber_wrapper br {<br /> display:none;<br /> }

turns off the line breaks in IE.

#flickr_badge_uber_wrapper td {<br /> background:#ddd;<br /> margin:0 !important;<br /> padding:0 !important;<br /> }
changes the background to something other than white.

#flickr_badge_uber_wrapper a {<br /> display:block;<br /> width:65px;<br /> height:65px;<br /> float:left;<br /> text-align:center;<br /> overflow:hidden;<br /> font-weight:bold;<br /> color:#111 !important;<br /> font-size:1.5em;<br /> line-height:2em;<br /> margin:2px;<br /> padding:3px;<br /> }

i wanted square images. i can't change what images get fetched, but all the images are wrapped in link tags (a), so i set the size of the link tag to the smallest side of the image, and then made the link tag cut off any extra. unfortunately, this means the link at the bottom of the badge is affected as well, so i also styled the text to be appropriate for a square link.

.widget_flickr table {<br /> background:#ddd;<br /> text-align:center;<br /> border:0 !important;<br /> width:100% !important;<br /> margin:0 !important;<br /> padding:0 !important;<br /> }<br />
this is where i really beat the thing into submission. .widget_flickr is the div that's created by the widget, whereas #flickr_badge_uber_wrapper is the id of the table inside it. they both affect the same stuff, but this way i can override the default styling. if i left it to the id, it would be overridden by the !importants in the default styling.

the style for the badge is loaded after any page stylesheets, including the CSS upgrade stylesheet. the background color and border cannot be changed.

i will let you know if this changes. i'm currently abusing the thing on my blog (click my name)
