I see some Newspaper , websites , Blogs post other company's logo , software screenshots ( googole , yahoo , photoshop , etc ) , photos , text ,etc . I just want do the same for non-commerical uses .
Except paying credit and using hyperlinks, how can I post them in my website/blog in a polite & legal way to ?
Thanks a lot !

usually you have to contact someone from the company asking for permission to post their logo or use any information that have on their websites…. i know that there are plenty of people who use companies logos and things without permission but it is not the right way to go about it… a simple email to the webmaster or someone should do the trick… most companies will approve it they just want to know what your blog or website is all about
