The model was downloaded with -hf option.

Problem description & steps to reproduce

Symptom:
Execute llama-mtmd-cli with --image option. it seemed it doesn't load the image.
No error messages when it loading the image, but when I send first query to the LLM,
it returned
"Please provide me with the photo! I need to see the image to tell you what's in it."
Judging from this message, it seemed it failed to load image when I specify it in command option.

Step to reproduce
(1) $ ./build/bin/llama-mtmd-cli --image /home/username/Repo/llama.cpp/dog01.png -hf unsloth/gemma-3-4b-it-GGUF:Q4_K_XL

(2) After initialize the LLM, I make a query.

Actual result

what is in the photo

Please provide me with the photo! I need to see the image to tell you what's in it. 😊 Once you upload or describe the photo, I'll do my best to identify the objects, people, or scenes within it.

Expected Result.

What is in the photo.

Here's what's in the photo:
It shows four dogs running in a grassy field. They appear to be having fun and enjoying themselves.

Additional information
After the LLM is initialized, I use /image to load the image file.
It works as expected.
For example,

/image /home/username/Repo/llama.cpp/dog01.png
/home/username/Repo/llama.cpp/dog01.png image loaded

What is in the photo.

image slice encoded in 778 ms

image decoded (batch 1/1) in 297 ms

/image /home/iida/Repo/llama.cpp/dog01.png
