Short answer
OpenAI’s guidance does not give a fixed number of pictures you can upload per day with ChatGPT Plus. It says image uploads are subject to plan-specific usage limits and account settings, but the guidance reviewed here does not specify a Plus-only picture count or daily quota. (help.openai.com)
OpenAI does specify a 20 MB maximum per image. It also says how many images you can add to a conversation depends on factors such as image size and the amount of text accompanying them. So there is no single per-message image count in that guidance either. (help.openai.com)
What limits are documented?
- Per image: Up to 20 MB. (
help.openai.com) - Images in one conversation: The number can vary with image size and accompanying text; OpenAI does not give one fixed count in its image-input FAQ. (
help.openai.com) - Plan usage: Image inputs are available on Free and paid plans, subject to plan-specific limits and account settings. OpenAI’s Plus page says Plus offers higher limits than Free, but does not state a picture-upload quota. (

These are distinct from a published daily allowance: the official pages reviewed here do not specify a Plus-specific daily picture count or a universal rate such as a set number of uploads every few hours. Availability can also vary by workspace settings, region, client version, and selected model. (help.openai.com)
Does a ChatGPT Plus upload limit apply to the API?
No—ChatGPT Plus and production API use are separate. OpenAI says API file uploads have separate requirements, supported purposes, and limits, and that API usage is billed separately from a ChatGPT subscription. For an API workload, use the limits and billing information for your API account rather than a ChatGPT Plus allowance. (help.openai.com)
