How are map layers supposed to work together?
In order for multiple map layers to work properly together, they must all use the same Coordinate System. The following directions will walk you through the process of checking your Map Layers/Shapefiles to find out which Coordinate System they are using and how to change them if they are different.
How to confine the effects of an adjustment layer?
To confine the effects of an adjustment layer to specific image layers, select the image layers, choose Layer > New > Group From Layers, and change the Mode from Pass Through to any other blending mode. Then place the adjustment layer at the top of the layer group.
How to make your image map resize with all its coordinates?
I think this is what you want to do. mapScale is designed to automatically change an imagemap to match the size of an image that you’ve set in advance through CSS. It sounds like you want to do something a little different – match the size of the image to the user’s screen. You need to first detect the size and then use resize to change it.
What are the advantages of an adjustment layer in Photoshop?

Paint on the adjustment layer’s image mask to apply an adjustment to part of an image. Ability to apply adjustments to multiple images.
Can a data layer be in two different coordinate systems?
However, in most cases you will be working with data layers in different coordinate systems. Every time you load a layer that is in a different coordinate system than your data frame, the program will warn you and ask you whether you want to transform the layer to match the coordinate system of the data frame.
How can I import two different coordinate systems?
You can choose a coordinate system from the list of loaded layers, import it from a (non-loaded) layer, or simply choose one coordinate system from the list available in the program ( “modify” option: geographic coordinate systems or projected coordinate systems).
How to tell which coordinate system a map is using?
Click on the Source tab. In the Data Source section, there should be a label that says Geographic Coordinate System or Projected Coordinate System. This tells you which Coordinate System this map layer uses. Check all of your other Map Layers to make sure that they are using the same Coordinate System.
