Treat picture as image

[DFGray]

If you are doing image processing, you may want to consider a different format than JPEG, if that is possible.  The JPEG compression process distorts the original image, resulting in changes to your image processing results.  If you can get the image in either uncompressed or lossless compressed format, in general, you will get better results.  The common uncompressed format is BMP.  Common lossless compressed formats include PNG and TIFF (TIFF is supported by Vision, but is not native to LabVIEW).  Note that your application may not need this, but it is something to think about.

Totally agree.That too when you are into measurements and into microns,I feel it is better to maintain a safe distance from jpg..........

Thx DFGray and Muks. With all respect to your advices, I'm not going into real advance measurement and microns this time. The manipulation for my image will be around doing some ROIs, overlay, rotate etc. Nevertheless, I really do appreciate your advice and I'll keep in my mind for my project in the future.
