Almost all web development
projects require photography, illustration, or maybe web template at
once. that’s why web developer needs a designer, to gather and meets
clients requirements, display an acurate, natural, original, and the
one and only works.. 
But sometimes, when times, human resources, and budget are constrained, some stock sites could be place to depend on. 
from stock sites we can find royalty-free photograpy, artwork,
ilustration, and web templates. its because, purchasing from stock
sites often costs much less than hiring a designer (on both times and
budget). 
As
a designer and a web programmer my self, i used to built the design my
self, or have others to design as a recommendation from my boss.
And actually i never download or purchased web templates from stock sites, coz i rather built it my self (Need some??? just call me 
).
But i used to purchasing those royalty-free images from stock sites,
coz i’m able to combine photos better than built it from zero. 
There are many stock sites with large collections and varieties prices (and better to choose the free one 
). here’s my favorite :

most of them can be purchased freely. Stock.XCHNG, the leading FREE
stock photo site. Whether you just want to browse our huge image
