I suppose that you are talking about a LV picture.
My opinion is that LV 6 was an absolute pity for picture management. LV 7 is only a pity.

Your problem could be solved in a breath using a few of the IMAQ vision tools. Unfortunately, NI has decided to keep separated its image management tools from its graphic development environment. I think that this situation should be discussed...

With LV 6, there is probably a solution that use the Flatten to String function, convert the string to a 1D-array of bytes, remove the 32 bytes or so the Flatten function has added before the actual picture bytes, then reshape the array according to the initial picture size. I have done that in the past for a 8byte picture. Not sure if it is as simple for a colored picture. Not sure either if I'll have some time to spare on the problem today.

Hope you will find here some more constructive help !

Also the extracted array was of 8-bit size and not any other bit length. no 1 bit or 24bit or.....
