please help me.

Did you Google for "no decode delegate for this image format"? I got 2,000 hits, with the quotes...

Next, if a poster has a harder question about Rmagick (or MySql, or JavaScript, or CSS), they should take it to the narrowest possible newsgroup. Not just the mighty and popular Rails newsgroup. You will get better answers.
