Hi there,  
This is my scenario  
1: I upload an image  
2: Without altering it,I make a copy of it and use it display to users in resized format  
note: I won’t display the original image.  
3:Now when user deletes the resized image,i need to delete the image loaded as bitmap i.e. the original image which i won’t be displaying

For that I used bitmap.bitmapData.dispose() method.But,it doesn’t free up the memory taken by the bitmap.  
For instance at initial state the memory usage is 58 Mb and upon loading 3 images the size increases to 87 Mb.  
And when I delete all the images the size decreases to 81 MB only.  
So,I feel the loaded bitmap is not completely removed.  
Any idea what should I do
