[ShowImage] takes too long to open an image

Mounted an NTFS partition (in read only mode) which has ~500 files of various file types. Double clicking some JPEG images takes about 8 seconds to open in ShowImage. During that time I can hear HDD seeking/reading noise. Probably ShowImage is trying to read the directory where this file is for caching.

Interestingly, opening the same image from Terminal using "ShowImage /path/to/image.jpg" takes 5 seconds. So there's some kind of a difference here about how the file is being opened.

Some other JPEG files in the same folder open within 3 seconds (using double click) in ShowImage.

It takes only 1 second to open the same file in QupZilla/WebPositive.

Opening it in DiskProbe is instant.
