I often generate static maps (.png) for offline use, but I also need the coordinates of the bounding box for it to be useful.
Any thoughts on this issue: https://trac.openstreetmap.org/ticket/4939
Some possible ways forward for this:
These coordinates could just to be displayed in the web page for the generated image, so that someone generating an image will know what they are.
Or if the server side code and configuration still supports it, a link to the old web page could provide this desired capability with minimal fuss. Is it still available and I have missed it?
Or embed the coordinates in the metadata for the image file. For .png, it could be added into the Comment field. http://www.w3.org/TR/PNG/#11textinfo
While on the topic, the openstreemap.org copyright should probably be included in generated images...
