Display more accurate error message when trying to attach image with non-image model selected

I had GLM 5 selected and wanted to attach an image to my message and got the error “Unsupported file type: (file name)”. I didn’t understand what was going on, because it was just a normal .png. Tried renaming the file, was about to get a converter and then…

remembered the model didn’t support images 🫡

It would be nice if the toast would say “this model does not support images” or something like that.
