Auto updating pic viewer
Visit Stack Exchange I have opened a picture with Windows photo viewer. How can I refresh the picture on Windows photo viewer? I went through the menu and couldn't find any action for it. If I open the image in WPV from the explorer AND leave the explorer window open on that folder, then WPV updates in about half a second.
Otherwise, WPV doesn't seem to notice updates to the file.
It supports all major graphic formats (BMP, JPEG, JPEG 2000, animated GIF, PNG, PCX, PSD, EPS, TIFF, WMF, ICO, CUR and TGA) and popular digital camera RAW formats (CR2, CR3, CRW, NEF, NRW, PEF, RAF, RWL, MRW, ORF, SRW, X3F, ARW, SR2, SRF, RW2 and DNG).
And yes, it auto refreshes when your file is changed on disk.
I just wrote a program, inspired by @Kit answer, with a few bonuses like retry, displaying last update time, etc. https://github.com/christianrondeau/Live Reload Image Viewer Windows Photo Viewer works just fine for me, but it's picky. If I open the image in WPV from the explorer AND leave the explorer window open on that folder, then WPV updates in about half a second.
This may be a bit unconventional but Sublime Text does this quite nicely.
I haven't tested it with many file formats, but it's working for a PNG file just fine.You will need to click through the User Account Control and a few other windows to allow the file to make changes to the Registry. Find Windows Photo Viewer in the list of programs, click it, and choose Set this program as default.
