Advanced Menu not showing

Hello. First time trying to put a map into roll20. When I searched how to align the grid every video and post said to right click the map, after selecting the map and background tab, and click advanced. I don't get that option, only Edit, paste and delete. Hopefully I'm just missing something obvious?

You only get the Advanced option on the menu when you right-click on an object. On the Map Layer, this will be the image of your map, either a tile or an entire map. Make sure your current layer is the same as the object you are selecting.

To expand on what Rabulias said:  Aligning map wiki quoted:     1. Zoom in to 150%     2. Make sure you're on the Map & Background layer      3. Right Click on your map image and choose Advanced -> Align to Grid     4 .Click and drag to trace a 3x3 (three across & three down) square box aligned with the grid on your map (we're ignoring the Roll20 grid for right now). You don't need to be pixel perfect here, but the more accurate the trace, the less fine-tuning you'll need to do later on.    5. When you let go of the mouse, a new window will appear. If you're satisfied with your tracing, click on the "Align to Grid" button to confirm.     6. The Grid Alignment Tool should resize your map to match fairly closely to Roll20's grid. Use the horizontal and vertical scaling transformers on your image to fine-tune the grid alignment. Aligning map wikipage .
