10.4: Use Spotlight to view missing 'image icons'
Authored by: Phosphor on Mar 05, '07 09:24:04AM
Something to consider, however, is that there is a reason many JPEGs are missing previews & icons. That is: since JPEGs are most often used for images to be displayed online, previews and icons are intentionally excised to tighten up the file size, optimizing them for fastest possible download.

Best move is to make copies of these JPEG files and—if you must—add the previews and icons to the copies instead, leaving the originals untouched.

Why? Because every time you re-save a JPEG you lose image data. If your goal is just to be able to identify them with a preview (say, in folder view), do it on copies, and leave the originals intact unless you need to edit them. And if you need to edit them more than once, convert them to PSD files.

Adding or removing previews with a dedicated preview-adding program (like the free CocoThumbX) does not affect the image data.
