There has been some postings about showing Jpeg photos on the Gigabeat. The complaint is that photos often are displayed very small on the screen I thought I'd just add some directions for how I get the photos to fill the screen.
Keep a copy of the original photos because you will probably be reducing their quality for use on the Gigabeat.
Copy all the photos I want to use in a folder on my computer. Then I use the free program XNView to see and change the size.
When a photo shows in XNView (not a thumbnail) ...
Go to EDIT - SET SELECTION SIZE - choose 3:4
Draw a rectangle on the photo with the mouse. Go to EDIT - then CROP. Photo is cropped to correct ratio to match the Gigabeat screen.
Go to IMAGE - then to RESIZE. Make sure KEEP RATIO is selected. Type 480 in the WIDTH. The HEIGHT should automatically give a number of about 638.
Save the image. Copy it to the Gigabeat. It should fit perfectly into the Gigabeat's screen.
If you wish to put a photo taken in a landscape direction you must first rotate it 90 degrees using XNView. Then follow the above instructions.
(After the photo have cropped, it may be possible to use a batch program to change the resolution. This will speed up the processing of many photos. I haven't looked into this. I think XNView has some kind of a batch program, though I've never used it.)
