What I do is make a template that allows me to copy and paste the needed image location. I have that template in my documents page and can copy and paste it into my post (It helps me if I forget how to do it). Then I go to the Images heading of Google and go to the photo I want to paste and click on it. It then goes to the section where you have similar photos with the photo you clicked on to the left. You can find other suitable photos in that section. The big photo on the left is the one you use to get the Image Location. This section also allows you to find which publication these photos come from. By clicking on each one, the photo appears in the left hand space.
The template:
img src=>
Copy and past your template in your post where you want it to appear. Right Click on the photo in the left hand space, and go in the menu to "Copy Image Location." When you Left Click on that menu item, you have copied the Image Location. Then you go to your post click between the = and > of your template you pasted and right click to paste your Image Location instructions between the = and >.
I got the following Image Location:
http://a4.files.biography.com/image/upload/c_fill,cs_srgb,dpr_1.0,g_face,h_300,q_80,w_300/MTE4MDAzNDEwMDU4NTc3NDIy.jpg
When I pasted the above Image Location, between the = and > I got this:
img src=http://a4.files.biography.com/image/upload/c_fill,cs_srgb,dpr_1.0,g_face,h_300,q_80,w_300/MTE4MDAzNDEwMDU4NTc3NDIy.jpg>
Notice the > is right after the jpg. That where you want it. Putting an < in front of img finalizes the Formatted Instructions.
If you have text, you want to separate your photo from the text. That is done by enclosing the letter "P" with the "<" symbol to the left and the ">" symbol to the left. It is like putting the letter p in parentheses like this (P) only using the symbols < and >. Put the P thing at the end of you text before your photo and make a space for your formatted instructions or, if you have text after your photo, put the P thing right next to your photo instructions, after the >. Make a space after your photo and type in your text. Remember, any time you format your post, you have to put the p thing after each paragraph.
