RPAEGE  I have used this for a long time now, and I hate to have to complain about such a great little free app, but it can't seem to do the first page of a PDF file if the file has more than one page. It always does the second page. Very annoying, but otherwise very use-able.

BRUMM  Huh? Tried without success, Terminal/Shell needed?

- Are you shure your comment is related to ThumbsUp? -

With the utmost probability you've gotta be kidding, but unless:

You _don't_ need the Terminal/Shell...

ThumbsUp is a standalone app, nothing else needed, maybe you are a bit alienated by its small file size of 704k, but it is a real app. - The programmers of ThumbsUp are high professionals showing huge knowledge not huge apps... they know how to code small, efficient and fast apps, it doesn't need some megabytes of code for such an easy exercise as resizing & sharpening images.

Again:

ThumbsUp is a _droplet app_, you start it by doubleclicking on it, configure your desired settings and then drop imagefiles on it.

It will do its job and after a short while your images are smaller/bigger related to your settings.

Just read the "ReadMe.rtf".

The one thing that you can't read in the "ReadMe.rtf", is just that ThumbsUp can not only sharpen the previews but the images itself.

Alright now?

TEKL  I tried it, but without success. I'm not very familiar with the Terminal/Shell.

BRUMM  This is the best resizer I've found,

ThumbsUp can not only create thumbnails or icons for images and movies.

ThumbsUp goes far beyond, it's a superfast batch image resizer, a format converter (for example jpg to tiff, etc.) and ThumbsUp can sharpen (!) and antialias (!) the images (not only the thumbs as falsly stated in the manual) and can do all that in one fast step.

...and this FREEware, wonderfull, thank you very much.

TEKL  Is this App scriptable or can be fired from the unix shell? I would like to use it for folder actions or droplets.

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.

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.

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.

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

BENZENE  Excellent little application, works fast and efficiently. Good interface.
