In case anyone asks, zenphoto is a piece of sh*t script! It keeps giving me blank pages for no reason. Just like that. I did not do anything to it and it crashed.
So I spent a few hours moving a lot of my pics to photobucket. I was paying for 25Gb of space and using only 300mb. And I do understand why services like PhotoBucket are making money. Because people want to put their pics there and do not worry about the script being hacked (happened two times with zenphoto) or something going wrong.
And 25$ a year is a good deal.
