[very noob] how do i find out the filename of an image object?

i’ve got a directory with 10 images. (image1.png, image2.png…)
I’ve written some code that when i tap a button, it shows the next image.

function button:tap( event )  
 if x == 10 then  
 x = 0  
 else   
 x = x + 1  
 end  
 myImage = display.newImage( "image"..x..".png" )  
end

I want to hide a button in image7.png that will take the user to another set of images.

i tried myImage.name == “image7.png” and myImage.filename == “image7.png” to compare filenames, but it doesn’t seem to work. How do i call the filename property (attribute ?) of myImage?
i just started Lua and looked but couldn’t find an example. I’m sure it’s out there…

Hi nimara,

you can extend an object with anything. So just store the filename inside the object.

[lua]myImage = display.newImage( “image”…x…".png" )
myImage.yourfilename = “image”…x…".png"[/lua]

Then you can retrieve it later.

Just be aware that, when you remove an extended object, a table with your extension is still left, so you need to remove it then too.
