How to load a second array?

Question

I have this code loading a set of thumbnails. Right now the
first set of thumbs loads fine but how to load my second array in a
new row?

Answer 1

Well my first idea would be that somewhere you are out of
scope and therefore you are getting an undefined somewhere in your
code.
So it might be trying to pass "undefined" as your url.
I would start with the debugger and step through the code to
make sure that it is able to get all the values it needs at every
step.
A good understanding of the debugger tool will save you tons
of time.
My next idea would be to split the code up using the command
pattern.
Also, since you only have two arrays, you could put an if
statement before incrementing the arr variable.
example:
if (arr < 2){
arr++;
}
