Here’s a little tip I got from a member of the Highland Lakes Computer Club Digital Graphics Group (Texas) that I’ve used innumerable times since it was posted several months ago.
When you’re sending an email and wish to attach or insert a picture, you select “insert>file attachment (or picture-in Rich Text)”. In the window that appears you are presented with the names of files, but unless you remember the precise name of the file, it’s very difficult to find the picture you want. Right-click inside the window and choose “View>Thumbnails”. Your files will be displayed as thumbnails, double-click and they will be attached to your email.
