Hi, great product! I've made some modifications, and have a few questions about modifications - any advice about what files would be best to modify to achieve these would be great!

I would like to have a "Show all markers" option that allows the user to see markers from all categories on the map.
I would like to auto-resize the image to a fixed height when uploaded because some users are uploading very large images.

Lastly, I was having some issues getting your auto lat/long function to work (it was adding things into incorrect fields, i.e. adding the town into the zip code box and other odd things) so I turned it off and am just using the "add hotspot" with no second map. But the users seem to be able to bad addresses or no address, blank titles, etc without any error prompt which results in hotspots added that don't show on the map. Is there any way to check for user errors with basic hotspot entry form? Otherwise I may have to come back and sort out the bugs from the second map feature.

Thanks for any help you can provide!
