The kaleido::save_image function parameters may not match this signature. The kaleido package typically uses different parameter names or structure. Verify the correct API usage for kaleido image export.

Suggested change

	kaleido::save_image(plotly_obj, file, width = 3000, height = 2400)
	kaleido::save_image(plotly_obj, file, options = list(width = 3000, height = 2400))

The plotly::save_image function may require different parameters than specified. Verify that width and height parameters are supported in this format, as plotly typically expects different argument structures for image dimensions.

Suggested change

	plotly::save_image(plotly_obj, file, width = 3000, height = 2400)
	plotly::save_image(plotly_obj, file, export = list(width = 3000, height = 2400))

Using 3000x2400 pixel dimensions for webshot may cause performance issues or memory problems, especially for complex plotly visualizations. Consider using more reasonable dimensions and scaling appropriately.

Suggested change

	webshot2::webshot(temp_html, file, vwidth = 3000, vheight = 2400)
	} else {
	webshot::webshot(temp_html, file, vwidth = 3000, vheight = 2400)
	webshot2::webshot(temp_html, file, vwidth = 1200, vheight = 900)
	} else {
	webshot::webshot(temp_html, file, vwidth = 1200, vheight = 900)
