I think the only way this would be possible in LV was if you convert the images to the LV picture format, flatten that to a string, send the string over and unflatten it and write it to a picture indicator.
There are several potential problems:
1. 7.0 was the first version of the PDA module. I don't remember how much support it has for the picture control, although I believe it should have enough. The newest version is 8.0, which was just released.
2. Depending on the size of the picture, this can be a lot of data. Since you have a g connection, that should be less of a problem, but it still may be an issue, depending on your frame rate. I once wrote a VI which recognized which parts of an image were changed and used a special (very primitive) protocol to send the data to the PDA (I was thinking of a cellular connection and wanted to minimize the amount of data), but I did that for the LV interface, which was mostly static, and I only detected that when it changed.
3. PDAs have significantly less processor power than a PC. Depending on your frame rate, this may be hard for the PDA.
4. The PDA module only supports 8 bit color, and that will require you to do additional computation to make the picture look normal. 8 introduced 16 bit support.
The upside is that writing the code for converting, sending, receiving and displaying the data is very very simple (assuming you can get it into the picture control format, not IMAQ, which isn't supported as far as I know). Just have a loop run on the computer side which will "acquire" the frame, flatten and send it, and another on the PDA side which will receive, unflatten and display. I think on the PDA side you will have to update the picture pixel by pixel.
