           Summary: [EDITING] When paste image on another image, they

           Product: LibreOffice
           Version: 6.4.1.2 release
          Hardware: x86-64 (AMD64)
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium

sample image file LibreOfficeLogo.png

When you paste image on another image, they are replaced by a strange
translucent box. The source images can never be recovered except Undo.Seems
identical or same cause with Bug 105066, but not sure so created as a separate
report, with some different reproduction scenarios.
 While experimenting around, Calc sometimes crashes.

Reproduction:
(1) Open attached image LibreOfficeLogoCaptured2.png with any paint app, and
copy it to clipboard.
  Any app will do. I tested with IrfanView 4.24(32) and Microsoft Windows10
Paint (version unobtainable!).
(2) Paste it to cell B5 on a Calc worksheet.
  Any worksheet will do. I attached 
  20200616ImageOnImageTest1a.ads
  for your comparison.
(3) Immediately paste it on B5 again. Ctrl+V, right-click, either will work

Result:
Images are replaced by a strange translucent box of the same outline of the
first image,
with red text inside saying "Image 2 ...".
Example  20200616ImageOnImageTest2a.ads
Reproduction 100%

Should be:
The image should appear as-is, overlapping.

Other observasions:
(a) As long as it is in the same session, no matter what you do between step
(2) and (3),
  it is reproducible 100%.
(b) Once you save the file and re-open, the existing images will not cause this
problem.
  But still if you paste a new image on that sheet, it is susceptible to the
same symptom.
(c) Can also reproduce by dragging on an image file onto the existing image on
worksheet.
(d) Reproducing variants:
  Before pasting the second image, click cell C5, which only partially shares
image 1.
  Paste image 2 onto the worksheet. Same syptom. Reproduction 100%.

Bug 105066 has a message from "QA Administrators" asking reporter to reproduce
with later version of LibreOffice. Appalling logic. These bugs will never
vanish unless the programmer consciously read the bug report and very
consciously address, repair and test. Then of course the programmer can update
the bug report status. If it is not marked "tackling", the bug surely is still
there. Hoping (or thinking that) bugs to automagically dissapear is
overoptimistic.
