UIImageView slows down app (in a news application)

I have a news application that gets the content from a xml stream- to every news entry belongs a picture.. which one i display in a table cell..

it loads all the content, but it looks like the image in the cells slows the whole scrolling down ..

any 开发者_StackOverflow中文版advice??

thanks in advance
