The problem is that when a record is auto-versionized the files of the record get copied and therefore get new names which is overridden with the names from the original record in the incoming data meaning both lost files and double-references!

                    // The versions uid is 456 and the file is copied to "logo_01.gif". But the form data that we sent was based on uid 123 and hence contains the filename "logo.gif" from the original.
                    // The file management code below will do two things: First it will blindly accept "logo.gif" as a file attached to the record (thus creating a double reference) and secondly it will find that "logo_01.gif" was not in the incoming filelist and therefore should be deleted.
                    // If we prefix the incoming file "logo.gif" with its absolute path it will be seen as a new file added. Thus it will be copied to "logo_02.gif". "logo_01.gif" will still be deleted but since the files are the same the difference is zero - only more processing and file copying for no reason. But it will work.

The copy always is re-calculated to have the correct physical measures as the HTML tag inserting it defines. This is calculated from the original. Two records using the same image could have difference HTML-width/heights for the image and the copy could only comply with one of them. If you don't want a 1-1 relation you should NOT use RTEmagic files but just insert it as a normal file reference to a file inside fileadmin/ folder
