Don't allow a message to post if an image upload is pending [solved]

From a message in a different forum:

rsirian1

Be careful.  If you upload the pictures and hit Send before they finish uploading the post won't have pictures but you won't know about it unless you check your post.  I think this happens a lot judging by the number of posts like this one.

If this is the actual problem, could the software detect the condition and prevent the error? Force the user to wait until the upload is competed or cancelled before allowing Send.

Hello,

The “Send” button has always been disabled during the upload of a picture.

I have put in place additional checks so that the message is not sent during uploads if you submit with other methods than the button, for example with Ctrl+Enter.

If you observe a different behaviour, please tell me which browser and version you are using.

I also verified the forum thread in which rsirian1 posted. No image was being uploaded when the message was posted. Either the poster just forgot to add a photo or something else happened.

 Yes, just seen while uploading a picture that the Send rectangle below the box 

changes to white during upload then blue when it is done. Thanks.
