Yousuf bhai! I have uploaded images on some hosting site. Then i have posted here using their links in IMG tags. As while posting, only text of IMG tag and link is visible, therefore one can write captions above each image.
While composing, the post looks like as following (Remove "**" to from IMG and /IMG tags)

Beauty of Lake Lulusar
