Yes, participles are a category of verbs that are sort of an verb-adjective hybrid: although they are forms of a verb, they can modify nouns. Generally speaking, the adjective and the participles will come after the nouns they modify. A difference between the adjective and the participles will be added automatically. In the sentence “Lots of people have his photo stuck on their wall”, the phrase “stuck on their wall” has a participle modified by a prepositional phrase, and together the participle+prepositional phrase acts as an adjective modifying “photo.” In the sentence “Lots of people have his photo stick on their wall”, “stick” is a right verb, and can’t act as an adjective.

The verb “stick” has the same form for both past tense and past participle, but with verbs for which those are different, past tense can’t be used as an adjective. Similarly, if I say “This is a photo seen by people”, but not “This is a photo seen by a lot of people”, I’m not sure I’m

the wrong person. But why should I not say “This is a picture seen by a lot of people” instead of “This is a picture seen by a lot of people”?
