Can I replace .JPG's used in a slide show with better copies?

Jennifer from "Choice Slides" was kind enough to answer this question for me.  The answer is "Yes!"  Here is her response:

Yes, you should be able to do this in the same way you did in ProShow, but......your images aren't where you think they are 🙂  Once you've imported an image into Photopia, it duplicates it into a different location (kind of like a Collect Show File).  So, when you update your original image in its original location, Photopia isn't actually looking there.  It's looking in the location where it duplicated the image.  THAT'S where you need to save your updates in order for them to change in Photopia.

Here's a video I made explaining where those duplicate files are.

Duane,

I have gone round and round with this issue and have found that the only way to insure the new/edited images are used is to do the second option that Jennifer talked about, "New Project". I save it to a different folder with a different name.

Photopia creates the "Data" folder but keeps looking elsewhere for the files.  I have changed images in the data folder to a completely different image with the same name only to see the old image show on the screen. If I delete the original image from the original location (still having a different image in the data folder) the program shows the original image on the screen and plays the original through playback. If I publish at this point the new image is used for the published show. At this point if I close the program and reopen the original image is on the screen, even though it is no longer in the original location or the data folder. If I look for information on the image from within the program it shows both the original & replacement, see attached.

So I do as I noted in the first paragraph and it seems to work. I believe this is all tied to Photopia's efforts to fix the "Missing Files" problem.

Yikes!  Thanks for the warning, Bob.  I'll have to watch this carefully because I don't know any way to determine, when I use the same image but better resolution, to see the pixel dimensions once Photopia is managing the copies.

You may have saved me a lot of time beause it takes almost 3 hours on my fairly high performance desktop to generate a BluRay .ISO file of this 50+ minute project.

Here is a new Q&A from Jennifer on this subject, not sure if you have seen it.

Thanks, Bob - yes, I saw it this morning.  Very helpful.  I have yet to try doing a mass .JPG overwrite to see if that works.
