Pineapple Pictures is a cross-platform, open source image viewer. Pineapple Pictures has an opaque interface, which is kind of cool. It may look like there are no visual elements in the GUI, but when you mouse over it a toolbar appears at the bottom of the window. The GUI doesn't have a title bar, scrollbar, status bar, etc. and this minimalist approach is quite refreshing,
Drag and drop an image onto the program to view it. Pineapple Pictures is a QT based application and hence supports many popular image formats including JPG, BMP, PNG, WebP, GIF, animated GIFs, and many others.
When you load an image two arrow buttons appear on the screen, one on either side of the picture. Click on the buttons to jump to the next or previous image in the same directory.
The 1:1 button on the toolbar enables you to view an image in its original size. If it looks a little awkward, switch to the maximized view by clicking on the 2nd toolbar icon. Zoom In and out using the mouse wheel, or with the help of the toolbar icons. If you are not a fan of the transparent background, click on 2nd button from the right, to toggle a checkerboard background to reduce the opacity. Rotate the image using the icon in the far right corner of the toolbar.
Right-click anywhere in Pineapple Pictures' interface to bring up its context menu. The copy sub-menu has 2 options, using which you can copy the image's PixMap to the clipboard. The other option sends the current image's path to the clipboard.
Want to browse your photo library while using other applications? Enable the "Stay on top" mode in Pineapple Pictures. Toggling protected mode prevents the program's window from being closed.
Click on the configure menu item to open the program's settings. Pineapple Pictures has just 2 options, one that disables the "stay on top" mode when you start the program. The other option lets you set the default double-click behavior, which can be used to close the program, switch to maximized view, or do nothing.
The properties menu displays the image's metadata such as the dimensions (resolution in pixels), aspect ratio, file name, type, path, size, date created and date modified. The text content in the property window is selectable, and you can use Ctrl + C to copy the data to the clipboard.
The image viewer used about 25MB of memory for the most part when browsing 1080p photos. The only time I saw the memory jump above 30MB was when I tested it with some very large images which I had, including some 8000 x 8000 files (30 MB images) in which case it used about 200MB, but that was to be expected.
Pineapple Pictures is an open source application written in QT5. The program is portable, and available for Windows and Linux.
Note: Windows will warn you whether you want to use the program, you can allow it. I scanned it using VirusTotal and it is squeaky clean.
If you want to browse your photo gallery without using too many system resources, this program can be a handy tool. But, Pineapple Pictures is a pretty basic image viewer, it lacks a slideshow setting, and it also doesn't remember the last accessed files or folders. Personally, the thing that annoyed me the most is the lack of support for keyboard shortcuts.
