I am sorry ..I tried it but I didn't resolve the problem..

Is there any another way to remove it?

The option [H] should work if you're using the float package. If you are using a special cls file, look if it's not specified in it.

An other way could be to not use the float package but to create a minipage and insert your figure in it.

It would be easier for us to help if you provide a short working exemple of the problem you meet.

This looks quite strange, can you paste the relevant latex code of the two images? The second image collides with the text block, that should never happen with a float. Did you use text placement that floats around images or something similar, or additional packages? What template are you using?

Dear Matthias Wilhelm,

I am using Sharelatex in online.

First image means X-ray diffraction is good and you can keep anywhere you want but coming to float image, If I write the latex code anywhere in the paper it's coming like this in a particular page.(wherever you given the image of the code).

But My point of view the Code is Ok.

But why I don't know.

I done whatever the possibilities I have but still problem remains.

It could seem a dummy question but did you checked your figure source file? Does it includes wide marging?

Again, it could much easier to help you if you share the part of the code where you have the problem.

I am have difficulty placing my floats under the text where I want them to be, LaTex seem to be arranging them how it chooses. Please how do I deactivate the float command or be able to place my image and tales where I want them?

Thanks
