Find the project here. Download the tar ball and install it. Description of the application is:
GTK+ collage, in short gollage, is a program to generate photo collages with a Polaroid photo frame. The photos will be place on the final image in randomly order. You can specify the degrees, the size of the photos and the final background of the image.
It is a very simple to use GUI application. First you need to select the pictures for the collage.
Once done with this, simply go to the settings window and specify the settings for your collage. You would need to specify the size of the final image, spreading of photos and maximum angle for rotation. Be careful in specifying the size of the collage as the images are not resized for the collage. So, if you want to resize the images do so, before selecting the images.
Now, press render to get the image
You can re-render by pressing \”recompute alignment\” or save the file with save as in the preview window.
