Hi,
I am implementing coverflow/slideshow type of application
I have 3 slots or layers for images to show.
I have to load 3 textures initially.
After any touch move event, i have to load the textures with new images.
For this reloading these textures with new image, do i have to delete the textures and generate new textures or can i reload in the same textures. (generate textures using gl.glGenTextures() ).

Please help me in solving this issue.

Understand what texture mapping can add to your scene
Specify a texture image
Control how a texture image is filtered as it's applied to a fragment
Create and manage texture images in texture objects and, if available, control a high-performance working set of those texture objects
Specify how the color values in the image combine with those of the fragment to which it's being applied
Supply texture coordinates to indicate how the texture image should be aligned to the objects in your scene
Use automatic texture coordinate generation to produce effects like contour maps and environment maps
