rssLinkList picture problem

In my Weblog I am using rssLinkList to show feeds from other sites.

Problem: When a feed includes a picture, the picture destroys the template.

I have tried to add following in the buttom of rssLinklist:
‘$rsslist = preg_replace(‘/(<img[^>]*)(src=[\”\’][^> ]*[\”\’][^>]*>)/i’,’\1 width=”400px” \2′, $rsslist);’

but then all pictures are resized to 400px and not only those that are too big.

what to do?

regards
