Quickly flip through photos/ thumbs on LExxB650 (USB stick)

If you're talking about Slide Show, it does have a Fast mode (and Slow) as well as Normal, controlled by the FF/REW buttons. Times seem to be about 2.5, 5 and 10 seconds.

Otherwise, you can move quite quickly through the thumbnails, once they're created.

Sorry for delay in replying. I was thinking about the thumbnails stored in mtd_contents, but that's only for video. I think picture thumbnails are created by the media server.

Maybe the problem is in the size of your pictures... 5Mb each implies a very high resolution, so the CPU has to scale down every picture to 1920x1080. This takes a time due to limitation in the ARM processor (which is not a quad-core) and RAM memory (you can not store a high number of snapshot as in a PC).

So I recommend you to create a directory which your pictures downscaled to a height of 1080 to watch them on your TV, and keep the original HR pictures as a backup.

jpeg decompression and scaling is done by hardware acceleration not cpu

I just connected a USB stick to check this, with a small sample of jpegs. For photos I took myself at 1600*1200 resolution, thumbnails are created for browsing within a few seconds. The ones that don't show are quite small files, created as thumbnails themselves for album art, though they can be opened and viewed OK. Maybe there's a minimum size, which makes sense if you're trying to create a smaller version of an original. From the other files found, I would say it might be around 100KB, but I had only a small sample.

As I said in an earlier post, only video thumbnails are created and stored on the TV. Picture thumbnails seem to be created on the fly, with no storage I can find by poking around in the directories.
