Nothing extra.
It is the original sample xImage01.prg from the sample-folder
You can test it from there.
For the test I added the image to the imagefolder thats all.
Just see the picture above

Master, this JPG is damaged. I opened it with IRFANVIEW.EXE and the image is not perfect. Try another one please.

I*m using a professional sofware PHOTOSHOP and there is no error.

Most of JPG-files don't use solid colors on the border-area.
That is the reason black is shown transparent.
With my new < cellborder-tool > it is possible to test it as well.
The image-selection from the browser is using xImage.

I tested some more JPG*s

the problem belongs to JPG-images with some SOLID colorspaces from the outside
Next I painted a SOLID freehand-border around image Olga1.jpg
A normal JPG without solid colors doesn*t have any problems





Images can be tested here :

Thank You very much
it is working now
solid color-areas are rarely inside JPG-files special on the outline area
