Not sure what you mean by "already was there in the Ganesha article" since, unless I am missing something, you added the image a few hours back, with a dubious claim in the caption. Note that the burden in on you to back up your claims with reliable sources, especially in featured articles where such information is especially liable to be removed. Highly encourage you to discuss the issue on the article talk page, instead on edit-warring to keep the image & caption in, since the latter is likely to see you get blocked.
