Hi I ended up using a JPEG in Memory Vi i found in the NI forums. Thanks for the help though. I'll try to make the picture bigger next time lol

Hi, I'm using the JPEG decode VI to decode an image string i'm receiving from a Blackfin Camera. This works fine when i run VI itself but when i use it as a sub-vi the program crashes .Anybody have any advice?? This is an image of my program this is how the file is returned from the camera 'I''##IMJxs0s1s2s3....'grab JPEG compressed video frame x = frame size in pixels: 1 = 80x64, 3 = 160x120, 5 = 320x240, 7 = 640x480, 9 = 1280x1024 s0s1s2s3=frame size in bytes (s0 * 256^0 + s1 * 256^1 + s2 * 256^2 + s3 * 256^3) .... = full JPEG frame Note that sometimes the 'I' command returns nothing if the robot camera is busy, so the 'I' command should be called as many times as needed until a frame is returned I modified the JPEG decode VI by switching the red and blue colour planes. I dont know whether this caused the problem though.
