Is it really OK for other sites to use pictures from POE?

On my never-ending search for those elusive photo places under another forum threat, I have hunted through many, many sites and came across one that appears to be using POE pictures without any credits to POE or links to POE site, that I could find.  While the photos are downloading (which takes forever) you can watch the various names of sites scrolling through at the bottom left of the screen, so it is not only POE photos being used but lots of aerial photos and other site photos. Is this in fact legal?  Should there not be some sort of credit shown to the POE site?  Some of the photos are "watermarked" so you can see where they came from, but we don't do that with ours.  If it is OK to pinch photos from other sites would it not be worth asking them to add a link to POE and enlarge the numbers brought to this site?  The site in question is: www.skyscraperlife.com.  Apologies to said site if permission was sought.

Who's photos are they using Cathy?    My photos are on other sites, but then, they are my photos, so i use them where i want to. The problem is, if they are using peoples photos off here without permission from the person that took the photos. The copyright belongs to the photographer.

Hey i've just checked this out Cathy!  your right!  its not so much a PoE issue, as an issue for the photographers, whos photos they are pinching! it looks like someone else will have put them on the site. But not asking the photographer is a no no!   theres some of mine on there!  i wouldn't mind if , like you say, they'd link back to me! but they don't, infering the photo is theirs!  fortunately my photos aren't big enough to really do anything with, i only post low quality images online, but thanks for the tip off!!

Thanks Cathy ML for alerting Chris and Sarah to this, they will be looking at it, if indeed they haven't already!

If you say that your permission hasn't been sought or given, and I am presuming that POE wouldn't have given this either, can anything be done about this person using your pictures without it?

It's certainly not alright CathyML. Chris and/or Sarah have not agreed to it and never would. I respectfully suggest you wait for a statement from POE unless of course you choose to take action individually, because it appears your pictures are being used without your permission, definitely not on!

Yes some of mine are there also, I do not think Chris and Sarah would have given permission without a mention to POE and also the photographer.
