Поиск по форуму не дает информации про этот сток.

поиск по их сайту и блогу тоже мало что даёт, похоже они в Ванкувере, существуют давно (блог с 2009 года, сайт с 1999)

I found some of your work posted on Behance and wanted to take this time to invite you to submit
your illustration imagery to ImageZoo. I particularly like your illustration
style and feel that your images would do well in our library.

We offer a great royalty rate, key-wording, file-processing and
distribution for rights-managed and royalty-free images. We also welcome
pseudonyms from artists that want to remain anonymous in the stock image
market.

If you are not familiar with ImageZoo, we are a Vancouver-based, boutique
stock illustration company. We work with close to 400 talented artists
worldwide.

If you would like further information or want to review our submission
package please let me know. I look forward to hearing from you soon.

And in the meantime, keep creating!
