Like I said earlier it ain't eazy at first but this is what I do.
I type in my text or some of it then I hit "submit reply"
I immediatlly go back to the post. On the bottom there is an Icon for "edit" I hit that.
When the edit comes up there is a box on the bottom "Go Advanced" I hit That.
I scrool down a ways, first comes "misc options" I go past that. Next is "attach files." I hit "Manage Attachments."
A new window appears. The top part says "upload from your computer" or something like that. In it is a Browse box. I hit that. That takes me to my computer. I find the pict I want to upload and double click on it. That will put it in the "upload file from your computer" box
I then click "Upload" Provided the file is not to big it will upload.
I then hit save changes and presto I have made picture on MM web site "Odd make eqivelent of fire." "Odd then happy."
And it only took about a week to figure this out.
Also in the help area there is a free pict. resizer. I highly reccoment it.
Good Luck, Oddfish
