I learned something new today. I stumbled upon a mosaic maker. It was pretty simple to do. I upload my image file and the mosaic generator pulls images from flickr to create a mosaic of my original image. I imagine that there are some real copyright problems with this use of the photos from flickr even though the mosaic generator puts a copyright notice on the Image Mosaic Generator site.
IMAGES USED IN THE MAKING OF IMAGE MOSAICS ARE COLLECTED FROM FLICKR AND COPYRIGHT OF THEIR RESPECTIVE OWNERS.
That said, you may want to go about creating your mosaic from your own photos. There are several ways to do it. There’s online tools that you can use your own flickr photos with (or any other online photos). Also, take a look at the popular software, Mosaic Creator, at aolej.com or ArcSoft Photo Montage.
