I'd assume the model is the same for both images? If so, you probably want .signature() with a Key that's unique to each image (an image id, incrementing integer etc). For more detail, see http://bumptech.github.io/glide/doc/caching.html#cache-invalidation.

what is a key in signature i dont understand it

[sjudd]

There are code samples, javadoc links, and a detailed explanation at the link I provided. Did you get the chance to take a look at that?
