Pixilated Finder's Icon Preview

[Sogni]

I've given up on iPhoto and have not found any program that will live up to what I want exactly, oddly Finder comes pretty close.
(I do use iPhoto for certain things, but not to permanently store/brose my pictures with)

So, I use finder with "Icon Preview" on and browse my picture folders... and every now and then I see something like this:



I can get rid of the pixilated previews by "Get Info", click-select the icon from within the Get Info Box, and close Get Info... then it shows the correct icon...

Is there a way to do this in a mass-scale? (I'll settle for directory-wide). Deleting the .DS_Store file does nothing, and I can't see any resource forks to delete when I do ls -la either...

Any ideas?

I believe the preview picture is stored in the resource fork of each file, which is why deleting .DS_Store won't do anything.

GraphicConverter's "Convert" application can do exactly what you want, and you can even specify how big the previews should be & other stuff too. You can have it do it to an entire folder, selected files, or entire folders with all their subdirectories. However, I think the unregistered version of GraphicConverter will do more than 10 files or something. It is a good app for a lot of picture stuff though...

I don't know how to do it for free or w/o GraphicConverter. Perhaps if you had an app that could delete all resource forks of selected files and then deleted .DS_Store so that the Finder would regenerate them?? I don't totally know what I'm talking about here though so don't try it unless you do!

Oh yeah -- using GC to delete the resource fork of a jpg file kills the icon in the Finder, so I'm pretty sure that's where the preview is stored. I'm just not sure how to force the Finder to regenerate them.

One more thing! If you are already using GC, I've found in the past that after editing or using a file in GC the preview icon gets pixelated like you posted. I think there is an option to disable this. There is at least an option to increase the resolution of the preview icon generated.
