I am wondering about the different previews for the same 'type" files. I'll backup a bit and say I am a bit of a switcher. I have very limited knowledge of Macs before OS X. I have come from the Windows/DOS/Linux world. I'll continue ... I have files, all *.jpg. When I look at them with "Super get Info", generally the type is "JPEG", but some have been blank. The creater can be different and this seems to infer which application will open it. Some have a thumbnail view of the image some have an icon. This seems to correlate to the size of the resource. I would prefer a more consistent view, like that thumbnail. What is happening? what do I do for a more consistent look?
