That's not good.
I thought that the members on here were honest and had integrity.
Maybe the site should move to not allow any images to be downloaded. And if a member wants someone else to play with their images, a PM will have to suffice.
There is a few on here that will download an image, have a play in photoshop, and repost it to show the OP what can be done. And some do it without asking first. Which I think is a real No No.
The site is getting rather large, and getting harder for mods and admin to police. Making the images on here undownloadable would be a better step for security, and members peace of mind.
