It is difficult for a new member. We have a lot of rules here, so you'll be spending a lot of time just learning them.
Here is the link to a thread explaining how to credit at tFS, in the Announcements Forum:
Crediting Rules: posting the source/credits for an image, article or news story Be sure to check out the other pinned threads while you are in that forum .... lots of things to learn for our members.
You need to state what site you got each photo from (your source), best to post it under each picture as you download them here. Do not post links to any site ... so make sure that you remove the www. and/or http or it will automatically turn into a link. Read the info in that link, then take a look around at how other members credit their photos ... most of them do it the right way.
So, now that it's too late to edit your posts ... you can just post a list of the sites where you got these pics in your next post ... if you remember. If you don't ... we'll ask you to start again and we will have to remove this thread.
Also ... if you want to learn about where to buy things, take a look around the Shop til you Drop forum .... lot's of threads there where you can get ideas and ask specific questions about things you have seen that you are interested in buying.
