It’s not that easy… I have all those sizes activated by the image isn’t resized for me either. See my settings…

But the media dialog shows only the original size available. The image is inserted at full size allthough thumbnail size has been selected for the gallery in the post.

Maybe PHP isn’t build with the proper settings? I’ve used the following during my last PHP update:
‘./configure’ ‘–prefix=/usr’ ‘–datadir=/usr/share/php’ ‘–mandir=/usr/share/man’ ‘–bindir=/usr/bin’ ‘–libdir=/usr/share’ ‘–includedir=/usr/include’ ‘–sysconfdir=/etc’ ‘–with-config-file-path=/etc’ ‘–with-exec-dir=/usr/lib/php/bin’ ‘–disable-debug’ ‘–enable-inline-optimization’ ‘–enable-magic-quotes’ ‘–enable-safe-mode’ ‘–enable-sigchild’ ‘–disable-ctype’ ‘–with-mysql’ ‘–disable-cli’ ‘–without-pear’ ‘–with-openssl’ ‘–with-apxs2=/usr/sbin/apxs2-prefork’ ‘–with-zlib’ ‘–with-zlib-dir=../zlib-1.2.3’
Any more ideas?
