This section lets you configure how the background picture itself is handled by JBS. Post-processing as well as picture selection is the main purpose of these options.
- Auto-rotate pictures if orientation information is present - some cameras know if you held your camera in portrait orientation and if they do they set a value in the picture saying so. If you enable this option JBS will figure that out and rotate the pictures the right way round.
- Orientation options - the following options let you choose the right orientated photos for you:
- Use landscape and portrait orientated pictures
- Use only landscape-oriented pictures
- Use only portrait-orientated pictures
- Try to match pictures to monitor orientation - Use an automatically chosen colour for picture borders - let JBS decide on a border colour for your pictures (only relevant when you centre or scale your pictures to fit the screen).
- Use a custom colour for picture borders - if you want to expressly choose your own border colours, this is the option for you.
- Apply this effect to the background - when this is enabled you can choose from a selection of post-processing options that will be applied to your background pictures as follows:
- None - doesn't apply any effect at all!
- Grayscale - makes everything black and white
- Sepia - applies an aged-photo sepia look
- Desaturate - tones down the colours to give a less punchy background
- Soften Colours - softens the colours,a milder version of 'Desaturate'
- Random - chooses a random effect to apply from the list above - Only show pictures larger than 'x' pixels - this lets you specify the minimum size of picture from either the folders your monitoring or from Flickr. It's a bit pointless having a huge screen and a tiny picture in the center of it, or have a tiny picture stretched to the full screen - it looks a bit blocky!
- Auto-centre full screen pictures if less than x % of screen - if you're opting for one of the scaling picture modes and a very small picture is chosen, then it'll look terrible scaled to fit the screen. This option will automatically centre the picture if that's the case.
- Use individual picture modes for each picture source - if you're a power user and prefer your Facebook backgrounds to be montages and all others to scale to fit the screen, then enable this option. Back on the Settings Dialog you'll now see a button to set each picture source's display mode.
- Cache montage and mosaic pictures for x hours - here you can decide how long the medium sized montage pictures are cached locally for. If you've got loads of hard drive space, make it a long time, otherwise keep it short, but note that JBS will have to download pictures more frequently.
- Cache picture lists for x hour(s) - here you can decide how long picture lists are stored locally for. These lists might be the results of an image search, a Flickr user's list of photos and so forth.
