I need to convert and display a JPEG image in LabVIEW l that I continously capture from Canon 1D Mark III camera using the Canon SDK. We have a dll wrapper for the SDK that downloads the images into memory so we have a pointer to the jpeg image stream and its size. Now we just need to convert the JPEG image to the IMAQ image type. The problem we're running into is that it appears the JPEG - IMAQ conversion functions are buried inside the IMAQ ReadFile vi. Unless I'm missing something simple is saving the JPEG file and reading it back with IMAQ readfile the only way to easily get a JPEG image into an IMAQ image? I also downloaded some code from the forums called IMAQ JPEG decode that converts a binary JPEG stream, but it has a couple problems including a big memory leak and swapping red and blue color planes. The JPEG image is 1024x680 32bit RGB.

Convert JPEG image in memory to Imaq Image

Also fine to be used with 2D picture control. Use "Draw Unflattened Pixmap.vi" from the standard picture palette (IMAQ not required) to convert binary data stream (32bppBGR or 32bppABGR) to picture.

It just occurred me, nowadays the functionality is provided, multiplatform, by G-Image.
