[BUG] Image paste fails only on Azure GPT-5.2-Codex (File not found / [Image 1] not processed)

Description

When using Azure GPT-5.2-Codex (gpt-5.2-codex on Azure) in OpenCode, pasting an image from the clipboard fails.

After I paste an image (e.g., screenshot → Ctrl+V), the TUI inserts a placeholder like:

[Image 1]

But when I send the message, OpenCode attempts to read a local file named Image 1 and fails with an error similar to:

Error: File not found: ...\Image 1

As a result, the image is not processed/recognized.

This issue happens only with Azure GPT-5.2-Codex. If I switch to GPT-5.2 (non-codex), everything works normally and the pasted image is processed correctly.

Suspected cause: This looks like a model/API integration issue specific to Azure GPT-5.2-Codex, where the image/file part is not being sent/handled correctly and only the [Image 1] placeholder text remains, causing downstream logic to treat it as a local filename.

Steps to reproduce

Start OpenCode and select Azure GPT-5.2-Codex.
Copy an image to clipboard (e.g., take a screenshot).
Paste into OpenCode input (Ctrl+V) → [Image 1] appears.
Send the prompt.
Observe OpenCode tries to read Image 1 as a local file and fails with File not found.
Switch to GPT-5.2 (non-codex) and repeat → works as expected.

Expected behavior

Pasted clipboard images should be transmitted to the model and processed normally (image recognition works).

Actual behavior

Only the [Image 1] placeholder is present at send time; OpenCode tries to read a local file named Image 1 and errors with File not found.

@InCerryGit 请问，opencode 如何链接 azure gpt5.2-codex ？我选择这个模型的时候只让我填写了 key，没有配置 endpoint 等信息的地方

文档中写了，配置环境变量即可 https://opencode.ai/docs/providers/#azure-openai

@InCerryGit try this [in provider]

the thing that solved it is
"supportsVision": true,

you can add PR to support it in the code
