Too often I have to select images with cryptic file names from a file chooser. Because I can't see the images I typically have to open the folder I am browsing separately so I can find image I am looking for, remember the cryptic name, and return to the file dialogue to select the file I want.
This could be easier if their was an option to view thumbnails, or to at least preview the image.
Developer comments
File preview is now in Hardy.
