I love that they are not only creating great content for my blog but also have tools to create beautiful images in seconds! It took me about 10 minutes of playing around with their tool set before it was clear what could be done using them (but even then i realized there were many more features than we needed at this stage).
They do charge quite some money ($199 per month) but if you're serious about wanting your own image library - keep looking. We wanted something simple as possible without too much hassle or cost involved so far everything has been easy to use. The team behind second street really cares about its customers which shows through every interaction.
