Photos to identify fish illness

[fishy luver]

I am wrighting a book identifying fish species and I was hoping to add in a section a fish diseases and I was hoping that I could get a few photos to put in the book. I am unsure of the copywright laws but if I can use any photos I will be more than happy to give credit. thanks in advance

If it should have any value then you need pictures of infected fish where the infections have been positively identified by a Fish parasitologist.
Pictures from hobbyists without a conclusive identification of the disease are worthless at best or may actually be harmful if identified wrongly.

Also, unless you are an expert in the fields of Ichthyology and Taxonomy and have ideally also phylogenetic data as backup, I don't know how you can be sure your fish identifications are correct, especially with very similar species or complicated families - clownfish and dwarf angels come to mind. There is a lot in flux right now and many family relations have to be reconsidered. Furthermore there are many unrecognized species hiding in plain sight. Several local color-forms may turn out to be species in their own right.
Writing an identification book right now may just be an exercise in futility - especially with all the online resources of today.

Here is HLLE:

The first 2 cases look both like clear cut Cryptocaryon irritans infections.
The yellow tang could have HLLE, but I wouldn't call it conclusive.
