Hi !
I did a search and i didn't found an answer for this, i'm planning to install Stramm to an existing galery because i want my thumbnails to have all the same size 80/90.
and i was wondering how are my existing thumbnails are going to look is it going to be possible to change their size too ? (i have more than 13 000 pictures on my gallery).
:)
You can mass rebuild thumbnails using the admin tools page.
Found it thanks !
