I was wondering if it would be possible to add a way to upload my own sky maps to view them as a layer among the different sky options. I deal with a lot of equirectangular maps that are in either ra/dec or galactic coordinates that would be interesting to see along with surveys and even to quickly investigate overlapping areas of interest. If there was a simple option to upload a jpg or png when creating a new row under sky select and specifying if it is in ra/dec or galactic that would be amazing. I would use it to plot sky models but I imagine others could use it to plot points of interest, observing footprints, or their own images. For example, in figure 9 of this paper there are some maps that (if plotted fully 90 to -90) could be simply mapped into ESA sky. If all maps are required to be full-sky as a standard it would likely be easier to integrate.
