in Photoshop :
Go to window -> path, if the path is named " work path " double Click on it and click OK ( the work path will be converted to Path to be used inside InDesign).
when you place the file in indesign, Go to Object -> clipping path -> Options or ( ctrl + alt + shift + K )
From Type: Select Photoshop Path as shown in the image below , Hope this will help.
Thanks for the suggestion! I did and yes it worked but for the old JPG photos, I could skipped the whole indesign step. I didn't have to go to "Object -> clipping path ..." or do anything special in Indesign. Just "place". That's it. That's what confused me.
In Paths panel in PS, go to the menu in corner of it and choose Clipping Path. Then select the path you want (It's name becomes bold in Path panel). It can't be work path so you need to rename it first. Then you don't need anything in ID.
That's it!! Thanks a lot!!
