Hello. I �m new to this website  and I have a question. The rules for uploading worksheets say that watermarked pictures can �t be used. Clip art can be used. And you can use copyrighted pictures with the permission of the creator.

 

Lately I have seen illustrations from text books and activity books, as well as scanned exercises. I only recognized them because I have used these books  myself. Futhermore, I sometimes used them before to create my own worksheets previous to belonging to this site. Is that permitted? I don �t want to be petty, I �m just curious. I don �t want to be one of those people who report every little thing, I just want the rules to be clean and fair to everyone.

Thank you.
