MicrostockGroup

If it was me I'd just delete the images to the extent possible (I know some of the sites only allow you to delete a certain percentage at one time, and Dreamstime has that 3 month rule).

To my knowledge there is nothing you have to send or request to delete your portfolio on any of the microstock sites, with the except of the sites that have retention policies as mentioned above. I have no idea why you would send a contract to end a relationship. You already agreed to contractual terms when you signed up and submitted the photos.

On Albumo and FeatPics, all it took was an email to get the account wiped wholesale at both places.

DT is a different story. There I just wanted a single image deleted from the database and they would not do it. The image is now in "disabled land" for an indeterminite amount of time. When I inquired about deletion, they gave me somethong about legal and liability issues, etc. Understandable, but's not like I was looking to delete 20 best sellers or an an account, just one image that never sold, that I wanted to reroute for different use. I figured it was safer to delete it than have it get reposted by me for sale in error.
