Here are some sample photo collages created using Vincent’s software.Ĭalled Shape Collage, this software is absolutely free, lightweight (~300kb) and it’s written in Java so it works just the same on Mac OS X, Windows and Linux machines. Vincent Cheung, who has previously worked at Microsoft Research and Google, has developed an automatic photo collage maker software that can create extremely impressive collages / posters / photo mosaics in few mouse clicks. The second good option is Picasa but this Google software doesn’t offer enough options to customize the generated collage image. I earlier recommended AutoCollage for making photo collages but the trial version adds a watermark to the final print.
