Invalid Image Path
Paths to the images in the Opticon file do not match the actual paths of the images
Correct the paths of image files in the Opticon file so they match the location where images reside.
For instance, if the images are in the location: D:\LFI\Customer-01234567, PROD01\IMAGES\IMAGES001\Investigation-01234567.tif, the relative paths in the Opticon file would normally be: Customer-01234567, PROD01, PROD01\IMAGES\IMAGES001\Investigation-01234567.tif
If the Opticon file has the relative path: Customer-01234567, PROD01, PROD01\IMAGES\IMAGES001\Investigation-01234567.tif, it will point to the folder that does not contain images due to the extra: PROD01 sub-folder path.
Open and modifying the Opticon file (via note editor like notepad or notepad++) by removing the extra PROD01 as followed will fix the issue since it's the same path as the actual images: Customer-01234567, PROD01\IMAGES\IMAGES001\Investigation-01234567.tif
