I have a question about the Image Gallery and I was stuck in a conversion.
Theres an exercise which i can't solve.
There's only 4 Photos allowed per row, so if someone uploads 20 Photos in 1 Album it must see like:
There are several solutions to this. Here are two simple ones:
1) CSS: Wrap all the Photos in a block (eg. a <div>) and set it's width to four times the width of a photo plus margin. Then apply float: left to the photos.
2) PHP: Write a function that checks if the current position is a multiple of four. Look here for a recipe: http://ssbits.com/manipulating-every-nth-item-in-a-control-loop/
