Would be good to reduce the CSV file size, it contains a bit too much repeatable data (symbiostock_image_info.csv):

Before 171 KB
After 128 KB (-25% )
zipped 30 KB (-83% )

So Leo you could remove these:

http://stock.imagerion.com/image
http://stock.imagerion.com/wp-content/uploads/symbiostock_rf_content

from

1711,RF,http://stock.imagerion.com/image/fight-the-flu-virus/,http://stock.imagerion.com/wp-content/uploads/symbiostock_rf_content/1711-hit-the-virus-v2.jpg,http://stock.imagerion.com/wp-content/uploads/symbiostock_rf_content/1711-minipic.jpg,No,No,Imagerion,"Hit the virus v2","Cartoon 3d human fighting the virus with the baseball bat - metaphor 2",4500,4200,"3d, 3d man, antivirus, attack, avian, blast, cell, character, concept, deadly, defense, destroy, disable, disease, disinfection, epidemic, fight, fighting, flu, germ, grey, healing, health, hit, human, hygiene, illness, immun, infected, infection, influenza, medical, medicine, metaphor, microbe, outbreak, pestilence, plague, red, serum, shot, spread, strain, therapy, vaccine, virus"

to get this
