Riverbyrnes, You can get my full name as download an image, but also if you want to contact me for anything special, I think you should contact one of the administrators and they will contact me. I do not know if are allowed direct contact so, I do not really know what is the policy in this case to dreamstime.
anyway I love to hear about your book, and soon in September I will have my own website with my own designs in 3D The site is under construction at this time. http://www.nightsurreal.com/
Riverbyrnes, you can contact Mega11 by going to one of his/her images and then clicking on the "Tools" tab (right next to the "Download RF stock illustration" tab). There is a field to send a comment which will go to Mega11. You may or may not hear back; it depends upon how often he/she is currently logging in to Dreamstime. If you cannot get the information you are wanting, you should be able to provide a credit line with the username of Mega11 and a mention of Dreamstime.
I love your work! I would like to use on of your pictures for the cover for a short young children's story - but for that, I need to be able to contact you as I'll need to (and want to!) credit you with the picture. I'll need your full name and contact details for that. But I can't find a way to send you a message direct on this site...
