Don't know this kid... But this website is a really simple and easy way to create collages!! As long as you have the photos saved and available for uploading, the rest is done on the website and you can download your finished product. And all the services I've used from it have been free. :)
Ever wanted to arrange a photo collage in a specific shape? You could create guidelines in Photoshop and spend hours arranging and rotating photos, or you could just use Loupe. Create collages based on shapes or words, all for free! Browse the gallery for ideas, or just dive right in and create your own. All you have to do to create is select your photos, pick a shape, and then arrange!
Fotor is vastly becoming one of my favorite online/app photo editors. This is a great tool where users can upload a image and then edit it w/ an abundance of different tools, effects, etc. Also, a person can create their own digital card through a wide variety of templates as well as beautiful looking collage. This is a very powerful and user friendly site for all your photo editing needs.
