JPEGs only please
Remember - the saver only handles JPEG format images. It cannot handle GIFs (well it can in theory but the licencing to an end user is very complicated for these and we cannnot legally give you the facility). Thus all images must have a file extension of jpg or the saver won't be able to find them.

Resizing
Firstly, if the images are larger in either direction than the screen saver can handle, it will resize them to fit. This nearly always results in very poor images as the pixels just aren't in the right places any more. To get round this, either uses images that don't need resizing (see below for sizes) or reprocess them

Reprocessing
If you have a decent graphics program that can edit JPEG format then you need to resample the images to the correct size. Resampling is not the same as resizing. Correctly done, there is very little difference between the original and smaller resampled image except for possible loss of text readability. Paint Shop Pro (fully working evaluations available) was used for the images we supply - the Image menu has a resample option and it's simply a matter of opening the file, resampling it to the wanted size (preserving the aspect ratio of course) and then resaving (without overwriting the original of course - straight into the directory structure described below would be best).

You may find that if your Image software has a Sharpen command, this will make a big difference to the quality of the picture after resampling (only sharpen it once though).

Where to put the images

• Create a new folder with the same or a similar name to that of the image archive you are going to create . This folder must be located at the same level as the 'default' folder off of the original installation folder. i.e. the folder hierarchy should look something like this:

Jag-lovers Screen Saver
    default
    my XKE pictures
    the Mk 2 archive
    my own Jag pictures
 
• Either set the configuration so that the saver looks specifically at this new folder, or set to Random so it picks up the new images. (If already running on Random you don't need to do anything more)

Image sizes
The saver uses images that are a maximum of 720 pixels wide or 540 pixels high (whichever is the limiting size).  So, for resolutions of 800 x 600 or higher, these are the sizes to aim for. No larger though in either direction - they'll simply get resized....

If you have VGA (640 x 480) then the above sizes will get rescaled. You need to resample to a maximum of 544 pixels wide or 408 pixels high to avoid resizing.
