xclip image binary contents pasted into text fields
I copied an image into clipboard with xclip like you did and here's what list of targets I got:
> xclip -selection clip -t TARGETS -o
TARGETS
image/png
and now if I copy an image from a web page I get this:
> xclip -selection clip -t TARGETS -o
TIMESTAMP
TARGETS
MULTIPLE
SAVE_TARGETS
text/html
text/_moz_htmlinfo
text/_moz_htmlcontext
image/png
image/jpeg
image/x-icon
image/x-ico
image/x-win-bitmap
image/vnd.microsoft.icon
application/ico
image/ico
image/icon
text/ico
image/tiff
image/bmp
image/x-bmp
image/x-MS-bmp
and for example setting target as text/html gives such output
> xclip -sel c -t text/html -o
<img src="..." alt="...">>
So obviously it's xclip problem as stated in prev answer
