Welcome to JThumbs!   SourceForge Logo

JThumbs is a pure Java application for thumbnailing, cataloging, browsing, viewing, and managing images on your computer.

I patterned JThumbs after a very useful application for Windows called ThumbsPlus. Since there didn't seem to be a Linux app with the functionality and interface I needed, I created JThumbs to replace ThumbsPlus. One of the biggest reasons more people don't switch to Linux is due to the lack of familiar apllications. My hope is that JThumbs facilitates the migration of more people to Linux.

JThumbs is far from perfect. The current features work fairly well. I'm going to work on the screen flashing next. If you have useful insight for making JThumbs a better product, please visit me at http://sourceforge.net/projects/jthumbs

Note for KDE2 users with Sun's JRE!   I developed JThumbs on a Win box, and then tested using Mandrake Linux 8.0. I had nothing but problems running GUI Java apps on this environment. There isn't much noise about it, but there is an incompatiblity with the Sun JRE and the KDE2.The problem is solved by switching to the IBM Java2 runtime environment. (You can actually have both, and edit your start scripts to use the IBM JRE).  The bug report is here.


Building thumbnails... Main screen view... Image open in viewer...

Using JThumbs & Features:

Use the directory tree on the left of the main screen to navigate to a directory containing images. JThumbs currently only recognizes the JPEG and GIF file types. Images in the directory will have a thumbnail representating shown in the right panel. To make all the thumbnails in a directory use the "make all" button in the tool bar at the top. You can select thumbnails in the right hand pane using familiar selection methods: "click" to select individual item, "shift-click" the select a range of items, and "ctrl-click" to add an item to the selected group. You can make selected thumbnails using the "make selected" button on the toolbar, or "F2" makes the selected images.

To view an image, double click on a thumbnail, or "click" to select, and press the enter key. When the image is being viewed, "F5" resizes the image to fit the screen, ("F5" a second time restores the image to original view), and "F4" switches the image viewer to full screen mode, ("F4 a second time swithes back to prior mode). "ESC" closes the viewer.

To delete an image file, "click" to select, and press the "Delete" key. Alternately, right-clicking on a thumbnail pops up a menu allowing deleting and viewing.

Image files can be moved from the current directory to another by selecting thumbnail(s) and dragging them to the desired directory in the left hand panel.

You can get file information about an image by selecting the thumbnail and pressing "I", or by clicking the "Info" button on the toolbar at the top.

The slideshow functionality is iffy. Select a range of thumbnails, then click the "Slideshow" button on the toolbar at the top.
