Hi ,

is there a way to change the setting that saves the images with a white border around the preview icon when one uses " Save for Web and Devices ? "

Thanks,
Robert

No, that's the default OS icon/thumbnail.

SaveForWeb doesn't including icons or thumbnails because it is minimizing the file size.

Hi Chris,

Thanks for your answer.

But sorry, I have to disagree. If I save a .jpg with "Save as" or "Save", the preview icon does not have the white border. Only when saving it with "Save for Web" does the white border appear around the preview icon. I'm enclosing a pic.

Thanks,
Robert

"save" and "save as" have the option to include a thumbnail (option is in preferences).

SaveForWeb does not include a thumbnail (because it is minimizing file size), and gets the default OS thumbnail - including the white border.

Chris is right, Save for web optimizes the filesize by not including a thumbnail, netting you the white border. "Save as" and "Save for web" are not the same thing, and are used in different scenario's.

In OSX, live generated thumbnails get a white border on *OS* level to indicate they had none to begin with. Photoshop can't help this behavior.

Ah , i get it . so this means it can't be fixed ?

Then that is why there's always a difference in file size when saving with the same parameters (say 70% compression or level 8 or 10) on "save as" and SFW ?

just the size of the preview ?

Yes, it's not broken, so it can't be fixed ;)

There are Applescripts out there that will add a thumbnail to any picture you feed 'em, but I guess you might as well use "save as" then.

I'm not privy to the internals of the compression used in the different Jpeg-saving magic, but I guess the thumbnail is a good start to explain the size difference.

I meant my heart is broken because my folders cannot display their contents correctly on my own machine ( correctly as in The way I want them ) .

;)

What I don't like about "Save as" is that it never saves the image the size it says it's going to save it.

What is the size of the thumbnail ??

And even "Save", when you "save" you get a window with the compression you want. It is always different on every image and if you just leave it the same, the image always ends up weighting more.

Save and Save As try to predict the file size in the case of JPEG, but can't predict the exact size of all the metadata (including thumbnails).

SaveForWeb minimizes the extra data it saves, and can do a better job at estimating the final size of the file.

The actual JPEG engine and compression is the same for Save and SaveForWeb.

When you feel like compressing your Jpegs further, I've had some(..) luck using http://www.jpegmini.com/

I guess predicting compression algorithms is really hard, otherwise they would have provided you with better estimates for sure.

#8 in this forum thread might help you out a bit, it describes how to make an autmator action to add thumbnails in the format you'd like.

Personally, I could do without the white-border distinction, too - but we need to take that up with Apple :)

This reply was created from a merged topic originally titled Photoshop: Thumbnails in OS X Finder have white borders around them.

i request the thumbnails should still remain borderless like they were previously as they have always been so you know they are edited. In creative cloud they still have the white border so you dont know if you edited or not. What a stupid decision adobe did.
