hello Erick

Not all-knowing, but I just tried an experiment 
and it works the same in Canvas and PhotoLine as 
you experienced with Photoshop.

It seems that the logic of the Mac is that if you 
make changes in a file then save it, it is not 
the same file although it is the same name, so it 
reverts to the default which you have left set, 
in this case, as Preview.

My I suggest two alternative work flows?

1)  Change he default for opening all JPEGs to 
Photoshop. When you want a quick look at a 
picture rather than launching Photoshop, click on 
the icon in the finder with the right button and 
go to "Quick Look" in the right button contextual 
menu. If you want to keep a number of pictures 
open at the same time, just select all the icons 
and drag them to the Preview icon.

2)  Store all your pictures in iPhoto. Use iPhoto 
Buddy to allow you to have a number of different 
iPhoto libraries. In your case, you would set up 
one library named "The Seekers" and keep all your 
Seekers pictures in it. Always use iBuddy to 
allow you to select the library you want to open 
and thus to launch iPhoto. in the iPhoto 
preferences, select Photoshop as the external 
editor. Then do your quick reviewing of pictures 
in iPhoto and your editing in Photoshop, saving 
back into iPhoto or saving out to another place 
if you like. You can also zoom photos for editing 
in iPhoto using the right button menu. (It is 
desirable to avoid editing in iPhoto as it 
applies rather savage lossy compression each time 
you edit and save and you have no control over 
it, so it is best to edit in an external program 
and save without loss back into iPhoto.)

In fact, I use the workflow described in 2) (but 
substituting PhotoLine for Photoshop) for 80% of 
my pix editing nowadays and it works very well. 
In iPhoto, I have several viewing choices; I can 
look at the minimum sized thumbnails or mak them 
all bigger with the size slider. I can look t 
each one zoomed to the max or I can look t a 
whole series as a slide show. Very handy. For the 
other 20%, I leave Preview set as the default 
viewer but when desired, drag photos on to the 
Canvas or PhotoLine icons to launch and open the 
pix for work, or I open pix from within the 
programs. I slso drag photos from iPhoto on to 
the  anvas icon if I want to use them in that 
program.

Kind regards
