To understand what I mean, please perform Manage Attachments, then click the Browse button, in this post, you should see something like shown in the attached image. A browse box to select files you like to attach. It seems like list with very tiny thumbs on the left to show images thumbs. - see attached image brwose.png -.
What I need is to make this scene to look like bigger thumbs and icons, something like you may see if you have could use MS Windows to browse file or even using nautilus to browse your file system - see attached image browse2.png -.
