Prior to Lion, I edited hundreds of images a week in preview. Mostly I'd open up a tiff that was several MB's and reduce the image size and SAVE AS a jpg with a little compression. Typically reducing the size from 5MB down to a couple hundred K.
I'd also use Preview to crop images and resave them.
Since Lion, these basic, simple tasks have become IMPOSSIBLE. I've used Mac's for many years without problems, but Lion is driving me crazy. Can anyone please help me figure out the workflow to do this basic operation?
Right now if I open a 5MB TIFF File I can't make any changes because I get a message saying the file is locked. So I must now Duplicate it within preview. After which, I'm working with a copy. I then resize it and choose Save Version. But when I go to save it I get this error:
Document "xxx" cannot be saved as "xxx"
then I get a message: Document "xxx" cannot be autosaved.
If I try to export the image, I get this message: Document "xxx" cannot be exported as "xxx"...
On the other hand, if I duplicate the file first in Finder, open the copy in Preview and make changes, when I go to save the file I get this message:
The document “keypad_5 copy 2.jpg” could not be saved.
Any ideas what the heck is going on?
The GOOD news is that all of this is fixed in Mountain Lion. Save As works once again. Kind of the best of both worlds now. Worth the $20 up grade just to solve the issue.
The other thing I found is that Adobe Reader has a way of causing issues when saving items in Preview. You might try removing it and seeing if that solves your issue. With the current version of Preview (OS X 10.8.2) I haven't needed Adobe Reader for many, many months.
Kudos to Apple, the listened and fixed a bad situation that I believe may have been exaserbated by Adobe Reader. Hope this helps.
