It's exactly what the message says: imagegif() is not defined - which means
you have gd without gif support. You will have to go to the install tool and
check the section "all configuration" for the graphical settings. After
changing the appropriate settings (especially "[GFX][gdlib_png] = 1") and
saving to localconf.php go to the Image Processing section and check if
everything works fine.

And next time do a search on google or typo3.org - this has been asked and
answered many times before.
