User has to compile “Name” with any text value, then he can choose the background colour and also a
background image pushing “Image…” button. In this case a new window will appear:
Choose an image and press “Ok”. When you use images the system has to send them to your client.
Depending on the speed of the connection the download procedure may take up to some minutes.
According to the client screen resolution the system will load up a new page. The real dimensions (width and
height) come from the monitor setting of the client itself. The system later is capable of dynamically resize this
value to show images and layers in a proper format. We strongly suggest to make some test before
proceeding with the complete layout design, especially using the real screen resolution of the local monitor
connected to the XWEB. Usually images are taken with a digital camera. Beware do not confuse this
resolution value (e.g. megapixel 3, 4 or more) with the one of your monitor (800x600, 1024x768 pixels). When
you take a digital picture your camera save it according to its setup. Once you download these photos to your
PC you need to resize them to the value you want to use in the layout.
Example Table 1
Digital Picture resolution File size RAW File size JPG highest resolution
2048 x 1536 (3-megapixel) 9MB ~ 1,10MB
2272 x 1712 (4-megapixel) 12Mb ~ 1,47MB
2592 x 1944 (5-megapixel) 15MB ~ 1,82MB
With a image editing software you can resize all the picture to the proper size. Size also means kilobytes to
download for the client. We suggest to use images not bigger than 40~50 Kb. Of course if you have a fast
connection you may exceed this value. File format supported are: JPG and GIF. We strongly suggest to use
JPG due to its better compression factor. As an example you can refer to the following table chart:
Example Table 2
File Resolution Compression ratio File Size
800 x 600 (outdoor image) 45% 64Kb
800 x 600 (outdoor image) 65% 44Kb
1024 x 768 (outdoor image) 45% 98Kb
1024 x 768 (outdoor image) 65% 67Kb
Actual file size, if you use JPG compression, depends on the picture you are compressing. Different pictures
with same compression ratio and same file resolution, may have different file size.
