i just created some folder like

images/albums/thumbs_40/
images/albums/thumbs_115/

and i added the albums images in the admin area, i choose the images browse, and save it ,
it displays the img in the admin area but not on the front area ...
whats the problem ? img size ?

and i just can upload the songs one by one in the admin area , is too slow, how to upload the 10 more songs at the same time ?

thanks a lot !
