hi everyone i am new to this site and i think this site is great , i want to know some very important stuff
i am starting a new website and i just found that this site is having great pictures which would suit my site , so as i was saying i will be required some images for my sites like header image, footer image and in all other areas where i can put the images from this site in my site . i just want to know that whether it is necessary to give the backlinks to this site if i use the images from this site . and also i will also be having a gallery section in my site where i will put some images from this site , is it ok or do i have to put the backlinks of this site in my site.
also i want to know whether it is necessary to post some amount of posts every month for using this sites images , i know this question is stupid but hey i want to clarify myself
thankyou

Hi Aki,

you are totally free to do with the images whatever you want; all things described are o.k.
Backlinks are very welcome but not really necessary.
Same goes for donating images

Best regards,
Stefan
