IAN LUECK  A nice drag-n-drop application that does what it advertises. It's saved me oodles of time, instead of copying a pic's image and then pasting it onto the file itself.

Only one thing: The newest version has a bug where if you distort the image in Preview (e.g. rotating left/right) and it already has a ThumbsUp thumbnail, it won't generate a new one if you drag it onto the application. You then have to do the copy/paste thing I mentioned earlier for thumbnail changes to be seen.

Otherwise, a good app.  (Version 4.1)

ARVIDTP  This is one of several god apps to do this - but it lacks the same feature all the other ones lack - the ability to recognize and skip layered photoshop files! This is a cool app and I dont want to bash it, but Just like every other one of these, it replaces the previews of layered photoshop files with white background and the "this is a layered file" text. I would like the ability to just ignore .psd files (which usually already have previews (because why not save one with the image when you are already saving in an largely-uncompressed file format that you're not going to put on the web or anything). That way you cold drop a whole folder onto the app without the worry of erasing useful previews of layered photoshop files. Thanks.  (Version 4.1)

BENZENE  This program is great. It's unobtrusive and fast. I use to to generate thumb images for my image gallery all the time, and it does the job wonderfully.  (Version 4.0.1)

ALICIA  Wow, this is amazingly awesome. It's so easy and cool, just drag and drop. I won't need another thumbnailer ever.  (Version 4.0.1)
