My next problem is, I want 5 images side by side of 250x167 of course with the text box. with a margin of 2.

1. With all the images inside 1 paragraph, it is best to put them into individual paragraphs. Select each image, starting iwth the first, then press the Right Arrow key on the keyboard to move the cursor to the right of the image, then press Enter to create a new paragraph. Do this for each image until each is in its own paragraph.
2. Place the cursor at the beginning and drag down to select all the images.
3. Click the Columns tool in the toolbar. The number of Columns should be equal to the number of paragraphs / images. Set the Stack Width to Small and Gap Size to Small and click Insert.
4. Click in each image, then select Figure from the Format list. Give each image a caption.
