Stock Photos in wordpress

The scope of this project is to make “Royalty free images” “free stock images”, we will be fetching images from readymade wordpress plugins I.E Symbiostock, Dreamstime, Pixabay etc. There are so many plugins available “WP Inject”. I would suggest searching for other sources of free images. On one side, we will be displaying “free image stock photos” with respect to PHOTOS, Illustrator, Vector “image filters or categories” all “royalty free images”, on the other side, we shall display Paid or commercial images as affiliates from photo bucket, dreamstime and as many affiliates as we possibly can. The most important aspect is to display commercial images with relevant query. I want a solution to fetch free images bulk images in wordpress and we will credit the “creator of the image”. In addition, we shall have the option to upload images as register users. The structure of the website should be similar to [login to view URL] and [login to view URL] Please provide me with relevant projects you have done so far in wordpress, moreover I would also require solutions to automate the process with minimal server load. In case of any hesitation, please feel free to ask anything!
