image copy paste problem

[surveyor]

PCLinuxOS MATE desktop Slimjet 19.0.4.0 and up to date Irfanview. I often need to copy/past images into Irfanview (image viewer) and this works perfectly in various other browsers, but not in Slimjet.
I can right click and copy/paste (the jpeg) into LibreOffice or GIMP with no problem but when I try to paste into Irfanview the paste option is greyed out.
In all other regards Slimjet performs really well so I would like to try to resolve this copy/paste irritation therefore, if anyone can throw light on it or suggest a fix, I would be most gratefull.

With Thanks.

in the browser go to settings

type clipboard into the search area at the top

follow the yellow highlights and drill down until you get to clipboard related settings; it will require scrolling and clicking a couple times

play with the settings and see if you can affect the desired behaviour

Thanks oftentired for your reply which came to nought but here is what I have just posted on the PCLinuxOS forum.

Still trying to resolve this and here is the latest.

Asked a question on the Slimjet forum but no suggestions worked.

Synaptic has installed a Slimjet update, great, but no change in the copy/paste.
I thought it might be something to do with Wine so looked at the Wine File Manager but it made absolutely no sense to me

Tried to find the clipboard to see what was showing, but could not find the clipboard, anywhere !

Synaptic again came to the rescue and I installed CopyQ, great, now I can see the images that I have copied.

Irfanview still does not have the Edit paste option activated until I right click on the image (in CopyQ) and select ''Move to Clipboard'' whereupon the Edit/paste option in Irfanview is activated and I can paste the image.

Although this resolves the issue I would like to learn more, so the next question is why does Slimjet not put a copied image onto the clipboard or why does the MATE clipboard not accept images copied with Slimjet.

Any enlightenment gratefully received.
