The 56k image should load. It doesn't have to be 69k just smaller. I just try and send it and if it too big I step on it and make it smaller. I used to have a version of Paintshop Pro that easily changed size and it gave the file size as a result. I'm not to PC literate so I just try and attach it to an email to myself to see what size it is.
