As far as I’m aware, the only way you are able to update an image via .csv data would be using a script. Try something like this:

function runWeatherScript(){
    app.beginUndoGroup("Run Weather Script");
    var masterComp = findItem("CHANGE TO MASTER COMP NAME",0);
    // Error check, makes sure script has a comp to target
    if(masterComp == null){
        alert("Master comp not found");
        return
    };
    // Import the CSV file 
    var csvFile = File.openDialog("Please select the CSV file containing the weather info", "CSV Files:*.csv");
    // Open the file and push all data into an array
    var csvData = [];
    csvFile.open("r");
    do {
        csvData.push(csvFile.readln());
    } while(!csvFile.eof);
    csvFile.close();
    //Loop through each line of the CSV file - start on 1st line of actual data
    for (var i = 1; i < csvData.length; i++) {
        // Seperate current row into each cell
        var curRow = csvData[i].split(",");
        // Variables for each column, easier to follow
        var city = curRow[0];
        var temp = curRow[1];
        var iconName = curRow[2];
        // Create copy of master comp for us to work in and rename to the city
        var newComp = masterComp.duplicate();
        newComp.name = city;
        // Change city text
        newComp.layer("CHANGE TO CITY TEXT LAYER NAME").property("Source Text").setValue(city);
        // Change temperature text
        newComp.layer("CHANGE TO TEMPERATURE TEXT LAYER NAME").property("Source Text").setValue(temp);
        // Get right icon
        var icon = findItem(iconName,csvData.length)
        // Change Icon
        newComp.layer("CHANGE TO ICON IMAGE LAYER NAME").replaceSource(icon,false);
    }
    app.endUndoGroup();
}
function findItem(x,length){
    for (var i = 1; i < app.project.numItems+length; i++) {
        if (app.project.item(i).name === x) {
            return app.project.item(i);
            break;
        }
    }
}
var csvData = [];
runWeatherScript();

It assumes all the layers you are changing are within the same comp and not pre-composed. Name the layers that will be changing in your project file and update the code to match those names. Let me know if any issues and I’ll try and help 🙂
