As I am sure the vast majority of you already know, picnik.com is shutting down shop in three short days. I have seen quite a few people in a bit of a dither over this, and I just wanted to offer my two cents on the topic.
Actually, it's not even two cents, it's totally free. As in, a free photo-editing program that I've been using for about a year and absolutely loving. I will be the first to say that I am not a photographer, but I do like taking pretty pictures of my family, and sometimes those pictures need a bit of tweaking (sometimes they need a LOT of tweaking!).
That's where Photoscape comes in handy. It is jam-packed with features, and...like I said...FREE.
Here is a screen shot of it in use on my computer (and awww...Jack dying eggs).
(And yes, you can make collages with it, use the "page" tab)
