I'm not certain it's Google. I just tried to copy/paste an image I posted on another site. That image was copy/pasted from my Apple Photo library into a post there (successfully). I tried to copy/paste from that site to here, but got that little question mark icon below.
Two different things are happening here.
First...You copy a photo from your Apple Photo library and paste it into a post on winemakingtalk.com (which is a Xenforo forum just like tvwbb.com). Xenforo is looking for filenames with extensions ending in .zip, .txt, .pdf, .png, .jpg, .jpeg, .jpe, or .gif. Since your photo has a valid .jpeg extension, it uploads and posts successfully on winemakingtalk.com
Second...You right-click on the photo in winemakingtalk.com and select "Copy Image", then paste it into a post here on tvwbb.com. Here's what gets pasted into the post:
https://www.winemakingtalk.com/attachments/1632880139037-jpeg.79279/
That's the URL to an attachment page on winemakingtalk.com that contains your photo. It's not the actual photo itself. When tvwbb.com tries to access that attachment page, it can't because it can't log into winemakingtalk.com.
So Jim, you need to copy/paste from your Apple Photo library to a post in winemakingtalk.com, then repeat that process for tvwbb.com.
Now, just to clarify one thing. You can copy/paste that attachment page URL into another post on winemakingtalk.com and it would work, because that forum can access and display the attachment page. Just like me going to my Glen Blue WSM page and copy/pasting the image of the cooker into this thread...tvwbb.com can access the attachment page and display the image here.
