webhops on "[Plugin: BJ Lazy Load] Everything working great except..."

Hi,

The plugin is working great on my site, but only problem is the image showing a little blur image with large text. Is that anyway to control the image quality that cached.

Also the cache folder getting very large, is that a good idea to get it cleanup once a while.

Thanks for the great plugin.
