I want to upgrade

[laurica]

Hello,

at this moment i have a 1.7.2 version which didn't make any trouble to me till now

i moved to another server and it has php 5.x and i get some error when i try to make new categories so i decided to upgrade to version 1.7.4

i have about 600 images and i don't know how to upgrade and keep the photos as they are

and also, will it work with php 5.x ?

thank you for your time

ps: if it was already answered, please point me to the right link (i couldn't find it)
