Since I am new to this forum, I have not much idea about framing the questions of right sort to this group? Moreover, I am unable to upload images in this page along with the question text. As I am trying to upload image from Android phone, I am unable to find enough option to include pictures here. Please help me Thanks in advance.
OK, I don't actually have the Android app, but I can tell you how to upload an image with images I found on MSE (click on an image to be taken to its source).
When you're in the app, you should see something like this:
There are several icons in the toolbar. The one you want is the camera icon, which will let you upload an image.
You then select an image:
Your image will need to be in an accepted file format. For example, PNG and JPEG are accepted formats, SVG is not.
And it will be inserted into your post. Your image must be under 2MB otherwise you will get a confusing error message and your image will not be inserted.
Note: On some sites (but not this one), users with less than 10 rep will not be able to inline an image (it will need to be a link).
