Problems with high resolutions PSDs

Some users report that if they add high resolution Photoshop (PSD) files to a Catalogue, the thumbnails come out as plain black images. It may also be an effect of combined large file size and resolution. There is no known work around for this other than to create thumbnails using a down-sampled version of the original (though note the Catalogue record will now show the image data for this file rather than the original).

One user has identified the scenario in which this happens, as well as a quick-fix.

Older versions of Photoshop (i.e. version 4 or older) did not have the option to embed colour profiles. Any RGB PSD saved without a profile in older versions of Photoshop will exhibit this behaviour with large file sizes. Newer files should not have this problem.

The quick-fix is to reduce the size by one pixel and resave the file with a current version of Photoshop. This "rewrites" the composite preview (and changes the file size of the image), removing the "corrupt" version. Simply opening and resaving the file has no effect.

There may be other ways to overcome this problem, including further manipulations of the image, additional hidden layers, or some other techniques that don't change the dimensions of the image. Experiment!
