thank you
I managed to modify the script so it takes all the various diacritics issues into account (not only the database, but also non-ascii characters in filenames made me a lot of troubles, so i had to add a function that checks the filename for A-Z 0-9 characters only and replaces any "invalid" ones). I have my website up and running, with some adjustments to fit our needs.
One thing that is still not clear to me is MEMBER / PERSONAL ALBUM. After i imported all the pictures from our Coppermine, all user albums can be found under PERSONAL ALBUMS list of PHOTOPOST HOMEPAGE. But, I cant browse to that via MEMBER page :
this
Fotogalerie Valka.cz - All albums
shows i have 38 pages of albums
and if I go for example letter D
Fotogalerie Valka.cz - All albums
i see some of them filtered by username starting by D.
BUT
when I go Member galleries, letter D
Fotogalerie Valka.cz - Member Galleries
i dont get anything.
New albums created in PHOTOPOST seems to work as expected and are assigned to Member galleries, but those old albums dont. I dont want to have this duality, which can be confusing to our users, how do I "upgrade" old personal albums from CPG to PHOTOPOST ones ? What DB change needs to be done ? Just hint please, i can update it by myself

, just dont know where to look.
