moving / reordering albums within an album

Using Gallery 2. I have a sub folder of the main gallery and lots of albums within the subfolder. I have loaded this summers pics ok but the album is on page 3 and i would like to move it to be the first album on page 1. I sis this previously (in April) but now cant seem to find the button to move the whole album. I can move the whole album to another sub folder, just not reorder within my subfolder. Perhaps we had gallery1 when I last did this but not sure... ! Many thanks
