In a directory of somewhere around 100 image files (all are TIFs, JPGs, PNGs which I scanned with the latest version of SilverFast and edited in Photoshop CS6), approximately 15% to 20% have blank icons and previews. The file data itself is fine and files open without problems in both Preview and Photoshop. When I view a directory with the icon view, Finder makes an appropriately-sized white space for the "phantom icon" and the grid is normally spaced. The missing icons occur in the following states:
- original scans from SilverFast
- These are RGB JPGs at 300dpi
Files range from several hundred KB to several MB in size - work in progress files edited in Photoshop CS6
- Edits include introducing transparency and layers
Out of habit I use TIF instead of PSD because PSD saves are single-threaded whereas TIF saves are multi-threaded - final files ready for use with InDesign
- JPG for files that do not include transparency
PNG for files with transparency
I rely on image previews throughout the Finder when selecting and placing photos in my book publishing workflow. Any ideas on how to resolve?
