Hello. I don't know much about technology and computers so I am hoping someone on here can help me.

I have a blog with blogger.com and whenever I put photos on the blog and combine it with text, before I publish the blog post it all looks fine and is how I want it to look.

After I press 'publish post' the post is different. Often there are massive gaps between the text and the photo and sometimes the text sort of goes all around the photo and looks stupid and is not as easy to read.

Does anyone know how I can sort this out please?

Thanks
