Images
There is a separate image channel that you can use to search images while video
is playing. Its channel number is 3. Search and play files according to the
Ethernet Control
section in order to use this channel.
Size
The supported image format is .BMP. Later versions of the firmware support
.JPG and .GIF. Create RGB 24bit bitmaps for best results. Be aware of this
when you are creating your images. Copy your images into the IMAGES folder.

For the IS:
To determine how big your images will appear on the screen, remember they are
sized 1 to 1 over an 800x600pixel window then scaled down to match the
window size of your video. So if the video is 720x480, and you create an 80
pixels tall x 60 pixels wide bitmap, it will cover one-tenth of the screen 800x600
screen. Then it gets scaled according to the diagram below, so you end up with a
72x48pixel image on the video screen. Use the formula to know how big your
image will be. If you are using PAL , substitute 720x480 with 720x576.

For the ISHD:
To determine how big your images will appear on the screen, remember they are
sized 1 to 1 over whatever resolution you have the monitor’ s output set at. If it
is 1920x1080 (default) you’ ll see the resolution relationship below. There is no
squeezing down on the ISHD, since it has a high enough resolution output. If
the image is larger than the window size, and the image is in CENTER
mode, it will be squeezed proportionally to fit on the screen.
