Hi @get and welcome to Mapillary!
The answer to your question is no - you can't use latitude and longitude only to access a specific image. This is simply because there may be more than one photo in the exact same location, so lat and lon wouldn't give a unique response. The photo ID is unique for each image.
Can you describe what you aim to achieve? Is it about that you are interested in a specific location and would like to render any image that happens to be the closest to these coordinates - or is it something else?
