No didn't work Frank.
I inserted an image yesterday from a local drive on a couple of occasions and the image upload worked and presented fine, other buggy issues with the forum app notwithstanding.
Are you selecting the insert image button and then selecting the location of the image you want to upload and appear, or are you trying to link one to a URL using the link button?
[br]Testing for you now. I am using Chrome on Win10 Pro x64 desktop.
Here (immediately below) is a example of an inserted image uploaded from my PC right now.
And here is a link to a different image, this one a link to one I only just uploaded Flickr's website especially for you. Click on this link to view my Flickr image
Confirming I can see both in the forum.
Were you able to see both?
