Hello Dan..
First of all thanks for your attention to my problem. I think that my problem is similar to the issues linked from you.
I try to explain better what's happen (sorry for my poor english).
First of all the images come always from clipbard... coming from Windows Tools Captur or GreenShot... (both disappear)..
From one pc the user create the file and put images (paste). When the files is delivered to me this images disappear...
I send you the file example where in my pc the images disapper..appearing in other pc..
Thanks
