Susan, this is how I do this:
-I resize all the photos to 800 pixels first, I think it's a good size when readers click on it to enlarge it.
-I upload all the photos first, in reverse order, so the last photo in the post is uploaded first.
-I don't like a lot of white space inbetween the photos, so I click the "edit html" tab and remove all the white space inbetween the photos. Each photo has a code that looks like this:
I delete all the empty space, so the code for the next photo comes right after the previous one.
-Then I start typing my text in "compose" mode. If I can't place the cursor inbetween two photos, I click the HTML tab again, and look for the place I want to type my text, and start writing there.
-If I want a blank line I write
or
for two blank lines
-I like my posts centered, so I highlight everything and click middle icon with the horizontal lines
For tutorials I like to have smaller photos, they are 800 pixels too, but I select "small" when I upload them and "none" instead of right, center, left... I upload 4 photos in one go, that way I can drag and drop the photos, and they can still be enlarged by clicking on them. Here's an example:

Difficult for me to explain this technical stuff in English, hope it's clear?
