i just tried this on my beta and i did not recive any error, album was created and images where put into album without a problem.
@rodolfo
Here is the steps to follow and test if you get same problem.
step 1: upload like 5 images and once it's done click on create a new album.
step 2: fill out info and click create
if lucky you will get like i got where album is created and pictures are moved into it.
If you get same error then it could server related by executing time is to short
so @Nirjonadda your problem seems to be more related to your php.ini configuration, i would guess execution time is to short or something.
