It's interesting to note that this member has put 6 of the systems in his small network of "5-10" computers in the V&M forum. Most of the threads are still active- however there may be a recent 'solved'. I have questioned the member who has agreed he has 'worn out his welcome' in that forum.
So asking a question here for a system that is being or has been worked on currently would seem to out of place.
Attaching an image requires one to save the image and use the Attahment feature, not the embedded feature. The second way requires that the image have a location that is accessible on the internet. Then doing a right click> copy image location> give the URL of the image that can be embedded using the 'insert link' icon.
A "small network of 5-10" machines would seem to me to be a work-related environment where an IT person should be available. Posting here to avoid using the IT and getting a quick answer seem to be a be a bit of abuse for the free, volunteer help we offer.
Surely someone is paying this person to maintain his "small network!"
