Can you modify Thinkstock images within the licence?
If I buy an image off of Thinkstock - can I create or redraw a vector version of it - if say it was a jpeg I purchased without worrying that I'm getting into any potential copyright difficulties later on. The new version of the image would be used in a commercial online product. I'm not really sure what the modify \ alter copyright situation is if I buy an image and then modify or create a new version of it.
This is with a standard one-month subscription. I'm sure this is in the licence agreement but I'm never sure I fully understand them - any help would be great.
