I wanted to email you in regards to the images used on our test shoot in 2015.
I recently found one of the images used on a beauty app, and after asking the company I then found that all of our images used on the test shoot were on Istock.

As these images are being sold, you needed to communicate this with me as I didn't agree to give you these images for commercial use, it was agreed on a TFP basis only.
A simple solution would be to take them down , but since they've been available for purchase and have been purchased for 2 years we need to discuss compensation for these.
Look forward to hearing back from you to sort this out. Thank you.
