Cathy,

I think there are two ways of doing this, one I believe stores the rotation in the thumbs.db file, the other actually rewrites jpg out rotated. If you copy the jpg out to a new folder and view it from there do you lose the rotation?

I just went through the process of working with 1100 shots from our vacation and rotated (using one of the two 90 degree rotation buttons) some of them right rrom the filmstrip view in windows explorer and they seem to be really rotated. The file timestamp was not changed though.

I think a some point it asks you if you want the rotation to be permanent or not and warns about possible image data loss in the process, but if you click that don't ask me again thing I'm not sire how you get it back so you can go the other way on the permanence selection.

>I have several image files on my machine (JPG). Some of them were originally saved portrait and others landscape. With Windows XP, I right-clicked and rotated the landscape pictures so they are now portrait. When I view the images in Windows, Word, VFP, and several apps, the image is portrait (like I want). However, in one particular application these images show up landscape.

>I'm guessing this means that some type of rotation factor is saved in the file and all other applications honor this .. but this trouble-some app does not. What I'm wondering is, first of all, am I correct in assuming that some type of rotation is saved in the file. Secondly, how do I .. using VFP ... look at the file on my machine and figure out what the saved rotation factor is so I can use that to fudge the printing in this one trouble-some app.
