Sometimes a fan just loves a celebrity or else wishes to remember the fact they were in love with a certain selection of celebrities and was an expert on their lives. To prove their fandom, they might assemble and protect their own celebrity photo archive and ensure that the archive would be protected forever. An organization might wish to assemble a photo collection in order to create a small museum.
Creating an archive means having a large number of photos, likely of a historic nature, and then preserving those photos. Likely candidates include pictures that were famous in their day, pictures that reveal personal traits of celebrities, and photos that might be rare. It is hard for a fan to get a hold of rare photos for lack of funding, but these pictures might be available on the internet for reproduction.
Speaking of reproduction, someone wanting to create a gallery might be limited to photos that are either in the public domain or that can be used for a reasonable cost. Celebrities live their lives in order to make money, and their image is often heavily defended in order to control who can profit from it and who can publicly display it. A person wanting to create a gallery of a living celebrity might find that agents want to control any public display.
If photos are for personal use or copies were purchased, then no one might stop the user from preserving photos in an archive. Preservation depends on the quality of the photo and the quality of the laminate. If the photo is being printed out, using high-quality printer paper is a much better idea than paper because the photo is actually a polymer.
Regardless of the media, it can be preserved very well if using a quality laminating material. This usually means plastic that is not too thin and produces a reasonably stiff end product. Laminating machines are sometimes a little expensive, and a professional laminating service might do a better job.
Photos can be temporarily preserved in sandwich bags, but they contain oxygen and so do not preserve photos as permanently as a good laminate. Picture frames preserve photos reasonably well, but again a lamination service will prevent atmospheric oxygen from causing damage.
Further services for a celebrity photo archive include having a rack to display pictures or else to have a time capsule. Sturdy metal jars further protect treasures from physical damage. These capsules do not have to be burried, merely kept on hand.
