Image Border Blend?

Hello All

Was curious if anyone knew of a handy plugin that lets you customize effects on images in pages/posts?

All I really want, to be precise, is to have the image appear to ‘blend’ into the site more, rather than just sit squarely on the page – to have the edges blur into the page/post background – etc.

Are there any plugins, that anyone is aware of, that allow you to do such things?

Thanks much for any assistance!
