Like in MS Win 32 OpenFileDialog - thumbnails with preview or details about the selected file.
Check the attached images for better clarification.
It would be ideal to display the image thumbnail for all type of files. However, at least, the most commont image extensions should be supported (*.png, *.bmp and *.jpg)
Please excuse us for the delayed reply.
Thank you for your feedback.
We will take this information into account when start working on this feature.
I'll also suggest to preview pictures inside the file list. Otherwise, what is the benefit to see files in large icons?
