Lately, I'm unable to paste any image into the body of any email I compose. I did not have this issue before today. Please help.

Question

Could this issue with not being able to copy and paste any image within the email body, be virus or malware related?
Though I don't think I have any virus problems. Also I have all the latest updates for Thunderbird.
I read some suggestions posted elsewhere and tried those but none of these worked :
DID NOT WORK #1 :
(If your Thunderbird email message is displaying strange-looking code (tags) after each link, images are missing (it looks like images have been stripped out), and the font appears different, or bold, then you’ve most likely changed the message body view inadvertently. To switch it back, simply:
Browse to View -> Message Body As -> and select Original HTML.)
DID NOT WORK #2 :
Email message looks fine, but doesn’t contain images
If the rest of your Thunderbird email message looks okay, but is missing images, or they appear to have been stripped out, it’s very possible that you’ve changed a setting that won’t let attachments (ie. pictures) appear inline (within the message body). To change this back, simply:
Browse to View -> and select Display Attachments Inline. )
DID NOT WORK #3 :
If you made the above changes to your Thunderbird settings and images still aren’t appearing in some of your messages, it may be that Thunderbird is blocking them because it thinks they are spam. To adjust your privacy settings and prevent the images from being stripped out, or not displaying at all (ie. being blocked), simply:
Click on the button to the above right of the email message asking you whether you would like to load images.
If the email message is from a trusted sender, you can click the link above the message specifying you would always like to load images in messages from this particular sender.
DID NOT WORK #4 :
If you’re still having troubles, or your changes aren’t being saved (ie. next time you open Thunderbird the images won’t display again) you can directly specify the default format Thunderbird should display email messages as in the config editor. To access it, simply:
Browse to Tools -> Options -> Advanced tab -> Config Editor
Search for mail.default_html_action and make sure it is set to 3 (allow original HTML). If you would like messages to open as text only (more secure, but you won’t see images, change the setting to 1).
Could you please suggest what possibly has caused this issue? Thank you for your time.

Answer 1

Thank you for your response.
After searching around for any pointers to my problem, the above fixes I listed were the things that came closest to maybe addressing the issue, that I was able to locate. But since none worked, and as you pointed out, it is now clear they will only help towards viewing sent images rather than helping with inserting any images in the body of the email, which is the problem I suddenly started facing today.
Coming to your suggestion, on opening the Write window, the Insert choice on the menu bar is indeed available. And I had already tried using that, by clicking on the '''Insert ----> Image''' option listed. That opens
up the "Image Properties" box but using that has not resolved the matter either. It results in an image box getting inserted within the email but without the actual image itself.
Plus, normally I am able to use the '''Paste''' function in the Edit menu or through right-click, but today the (Cut/Copy/Paste) functions have gone inactive, thereby disallowing me to use that to place an image within the email.
