using IMAQReadFile with .jpg format of file is producing an "incompatible image size" error ?

[FraserD]

The .jpg monochrome images are of slightly different sizes. Is there a way round this or should i use a different file format ?

I trimmed down your code a bit, but I don't see any problems with using various sized images. I ran your code first with no changes except removing the text file IO and changing the paths and saw no problems. I am using LV 6.1 with Vision 6.1. Take a look at the code below and see if it works for you.
