If you have the picture or drawing on your PC, e.g. jpg, png, pdf, etc., then goto
postimages.org (no account needed). Make sure "Do not resize my image" and "Never expires" is selected. Then select your file to upload. It will then offer a bunch of links - copy the "direct link", the second one down, by clicking the blue icon to the right of it.

Now return to your eHam message where you want to insert the picture. In the eHam tool bar, select the insert picture icon

. Paste the copied link between the two IMG tags. It should look something like this:

. Select "preview" to confirmed it worked.
You can see how I put these pictures in this post by "quoting" my post. All the image tags will then be visible to you. After you looked at them, just use your browser's back button to cancel the quoting of my post.
I have shown to the eHam administrators how this can be integrated with a single button into this site and they have ignored the suggestion. They don't seem to care.
