Hi Mark,

this is a really, really annoying bug and you have to manipulate your
images after getting them from the database with GetPicture, because
there is no way you can prevent SetPicture from changing your pictures.
This seems only to happen to 32-bit images, though.

It seems like the first pixel column to the left gets appended to the right.
so here's what I do to compensate it, works pretty fast:

    -- strip right pixel column (workaround for V4MD/Jpeg lib Bug)

    -- get image
    myImg = pMem.image.duplicate()
    myWidth = myImg.width
    myHeight = myImg.height

    -- copy right 1-pixel column to the left side
    srcRect = rect(myWidth-1, 0, myWidth, myHeight)
    destRect = rect(-1, 0, 0, myHeight)
    myImg.copyPixels(myImg, destRect, srcRect)

    -- crop right 1-pixel column and set image
    pMem.image = myImg.crop(rect(-1, 0, myWidth-1, myHeight))


Maybe it can help someone.
