thunderbird will not send email that has a jpg or png

As stated in the subject line, on my PC Windows 10, I cannot reply to an email that has a jpg or png in it. I have to delete the jpg or png for it to send. I don't ever use or install these in my emails, but a lot of people put their credentials in a jpg. So I have to delete them to reply. I get an error message stating that. Weirdly, I have Thunderbird on my Macbook Pro at home, and this is not a problem. It is not the Anti Virus. I have Windows 10 Home Version 64 bit. My Thunderbird states that it is the 32 bit version, but I read that doesn't make a difference. This is the message I get.

Sending of the message failed. There was an error attaching image001.jpg. Please check that you have access to the file

Yes, I do think it is anti virus related.

Prior to sending a number of temp files are created....my guess is the anti virus is actually locking the file in the temp folder for slightly to long and the send fails because the image file is not available for incorporation.

I rebooted to "safe" mode and still have the same problem, so it is not the Anti Virus. Any other thoughts?

Image would get saved to a Temp folder. If testing on same email and the image file is still stuck in the temp folder then you may still get the error.

search for a temp file on computer eg: UserName/ AppData > Local > Temp that has the image001.jpg file and remove it. Then attempt sending.

That didn't fix it. There wasn't an image001.jpg file in any of them. In fact, I did a search for that file on my system, and there wasn't any.

Still can't reply/resend an email that has a jpg or png in it. Thoughts? This is not a problem when using my Macbook Pro.

temp files are just that temporary. Windows hides the temp folder and it's contents, so searching is actually useless for locating anything in it.


What anti virus are you using?

Was that Thunderbird's safe mode or windows safe mode with networking? See below if you need the details on which is which

  • Restart Thunderbird with add-ons disabled (Thunderbird Safe Mode). On the Help menu, click on "Restart with Add-ons Disabled". If Thunderbird works like normal, there is an Add-on or Theme interfering with normal operations. You will need to re-enable add-ons one at a time until you locate the offender.
  • Restart the operating system in safe mode with Networking. This loads only the very basics needed to start your computer while enabling an Internet connection. Click on your operating system for instructions on how to start in safe mode: Windows 10, Windows 8, Windows 7, Windows Vista, Windows XP, OSX
If safe mode for the operating system fixes the issue, there's other software in your computer that's causing problems. Possibilities include but not limited to: AV scanning, virus/malware, background downloads such as program updates.

Restarted Thunderbird in Safe Mode w/ Add Ons Disabled, didn't fix it. As stated before, I rebooted the computer in Safe mode with networking and that didn't address the problem either. Bitdefender is what I am using. I contacted them at first because the Anti Virus was suspected as the problem, but they walked me through rebooting in Safe mode, which made no difference for my problem.

I don't know how to explain this but.... With this ongoing jpg png problem, an accidental notice happened. I copied an email an email address, and when I went to send it I got this jpg can't send error message. The other weird thing is that it didn't have the usual image001.jpg, it had some weird file name, blahblahblah.jpg, not really but something random. And there weren't any jpg's in email, usually I have to delete them before sending. Thoughts?
