[solved] hi ! (sorry for bad english/french here...)
maybe an ever n ever posted quest... we'll see
i first generate a gallery with default WP option (150x150px)
all looks correct, really (shadowbox-js does the rest), ok
then i decide to have bigger thumbnail and change my WP configuration in prefs.
dunno why, if sthg buggy w/ me, but i have to create another n same gallery 'cause first still the same (with small thumbnail)... for one gallery it's ok, but not for 10...
anyway, i'll again take a look in the forum, but until now, nothing !
sorry for trouble if redundant post...
ps: a plugin does that... sorry regenerate-thumbnails
include in next WP 3 ? bye ! (shame on me)
