Put all his pictures together with a pretty bow around them. If you go to a walmart or any dept store in the craft section, they have really beautiful clothe colorful ribbon there. You may even find a nice box that will fit both pictures and toys. Some boxes come with a little slot to slip a photo into so it shows on the outside. Sounds like this great guy is going to be with you forever so it may help in the long run to both honor him and start putting his life together the way you remember? Maybe it is too soon, if so I am sorry to suggest this but you can put it on the back burner (I have 3 cremated cats here with toys and photos- it helped me some to gather the things and photos...).
