Hi Satya

You can add renditions to any image using AssetManager/Asset API . Please refer the below API for more help Asset ("The Adobe AEM Quickstart and Web Application.")

Also for custom thumbnail we can use RenditionMaker or Asset Handler.

By RenditionMaker, we can associate an Asset "X" with Asset "Y" as a thumbnail.

// Create the Rendition Template for thumbnail
RenditionTemplate[] templates = createRenditionTemplates(tempThumbnailAsset);
// Generate thumbnail
renditionMaker.generateRenditions(asset, templates);

private RenditionTemplate[] createRenditionTemplates(Asset tempThumbnailAsset) {
        ThumbnailConfig[] thumbnails = new ThumbnailConfig[1];
        ThumbnailConfig thumbnail = new ThumbnailConfigImpl(48,48,false);
       
        RenditionTemplate[] templates = new RenditionTemplate[thumbnails.length];
        for (int i = 0; i < thumbnails.length; i++) {
            ThumbnailConfig thumb = thumbnails[i];
            templates[i] = renditionMaker.createThumbnailTemplate(tempThumbnailAsset,thumb.getWidth(),
                                thumb.getHeight(),thumb.doCenter());
        }
        return templates;
}
