Generally speaking, as long as you give the proper credit to the source it should be accepted. I will say that if your hubs are not written better then your question you will not get a lot of readers. some people will obviously go to your hubs and even leave compliments and other comments, but to get repeat readership, you need to be more clear in conveying your thoughts. I mean this to be helpful, so please take it that way. You are asking for advice, so I know you're interested in improving your writing and hubs. When it comes to pix, you need to include the sources just like if you quoted someone or used another source. Literally speaking, if you use a photo from an internet source, you need to copy the URL into the hub when you upload the photo. Let me know if you have any other questions or if what I've said doesn't make sense. Good luck with your Hubbing!
