Posterino enables you to design and share your own picture collages, calendar models, e-cards, and many others. The program provides you with a user-friendly interface, gives you access to various design templates, and offers you quality output files in no time.
This utility supports multiple input formats, lets you use drag-and-drop actions while rearranging your pictures, and brings you many output settings to help you get the exact results you need. You can attach text content to your collage or even postage stamp, choose the preferred page size for quality printing, and so much more.
Once you finish editing your project, you can either share it via email or Facebook page, export it to your local directories or print it directly from the tool's interface.
The only thing that bothers me is that it supports a very small amount of output formats: PNG, JPG, and TIFF. Still, these file formats are very popular and supported by many Mac programs.
Hence, Posterino provides you with a quick and simple way to generate photo collages on your Mac. It's worth buying this product if you plan on using it often.
