Hi,
It would be a really good improvement and save us a lot of time if it where possible to get a large preview of image files when hoovering over the thumbnail and/or filename in the attachments tab.
Since FLC already creates a thumbnail really quick, it should be possible to create a "bigger thumbnail" for preview reasons.
This would save us a lot of time when trying to find and view the right image.
As a side note, if possible - it would be really awesome to get the same preview functionality on all kinds of files - e.g. a PDF where the preview shows the front page.
