Copyrighting copyrighted pictures can be a tricky business. If you have permission to use the picture from the copyright holder, then using it in your blog is perfectly legal. However, if you don’t have permission to use the picture, then you might be infringing on the copyright holder’s rights. Ultimately, whether or not you can use a copyrighted picture in your blog will depend on the specific situation.
For example, if the picture is part of an article that you are writing, then you likely have the right to use it. However, if the picture is used purely for entertainment purposes, then the copyright holder might have more rights to protect it. Ultimately, it is important to contact the copyright holder to get their permission before using any pictures in your blog.
