The program is easy to use and needs no advanced or complicated settings. It opens with a file browser that can find and display all pictures from your system, or you can add a certain folder using the file menu and start see your photos in slideshow. On the left side, you have an optional category bar from where you can organize and group your pictures by assigning different captions and ratings to them and by embedding IPTC keywords in order to store all metadata. It's easier and saves you a lot of time. Then you can use the search bar to find faster a desired photo or more photos from the same category.
Double clicking on a picture thumbnail will open it a viewer window, from where you can print photos or email them and apply some basic retouches such as changing brightness and fluorescence, cropping and auto-fixing an image. You can also enhance pictures by yourself; the fix image feature allows you to adjust brightness and contrast, hue and saturation, to sharpen and blur, to remove red eye and to apply few effects, such as negative, sepia, grayscale or black and white. The tools menu gives you access to some other practical features; you can batch convert missing files and batch resize and convert images.
PicaJet Free is not an advanced photo editor, but it is really helpful when it comes to managing your picture collections, because the organize menu is well structured.
