There are some pictures i dont want my users to download. How can i right click block ? Or is there any setting for permission of downloading ? Thx
There are scripts that disable right-clicking, but they are plainly stupid. If you must have them, search the board, as this has been asked many times over.
As suggested above, we don't recommend applying them.
It lies in the nature of the www that if you can view an image, you already have them on your client. There's little you can do against this. You might want to watermark your pics - it's the best protection against content theft.
How can i do that because there are some pictures i do not want my users to download.
Here is the Watermarking & image manipulation board

Even better solution is watermarking on the client before upload, using tools like Picture Shark (http://www.picture-shark.com/) or similar.
