By chance really. Searching for a suitable image for a new web design, I googled for "green wave" and found an image from Dreamstime. What stuck me most was the abundance of superior quality vector images available here.
In the end, the web design with the green wave and all was accepted for implementation. Which also means we had to buy the image. So, a paper had to be put up to convince the bosses that we need
a Dreamstime account. Yeah, we do. And that's how we ended up here. A shared account, no doubt but still, it is satisfying to the inner designer in me to have access the the stock of good quality images.
