# How do high-resolution images affect the OpenAI API context window?

I’m trying to estimate the context usage for a request that includes several images, not just text. If those images have very different dimensions, does the API treat them differently from a context-limit perspective?

I’m especially curious whether sending one high-resolution image can use noticeably more of the window than sending a few smaller images, and what developers should check when a request with images hits a context limit.
