I sat down a few weeks ago to figure out the best way to anchor pictures. Specifically, how to do it in a standard context like this. You have a paragraph or line of text describing something, and you might then say "....as shown in the following illustration." Then you have a picture on a line by itself. No wrapping or anything, very simple. Like this.
The horses at the Kalispell Dude Ranch are well-trained and gentle.
A very reliable way to do it is by anchoring As Character.

Anchor As Character treats the graphic like a letter. Which means you can't drag it around, but that you can position it using the text alignment and indent features. And the less dragging, the less it is likely to be a little Skittery.
How to Use Anchor as Character
Step 1: Insert the Picture.
Create a blank line for the picture by pressing Return after the text. Choose Insert > Picture > From File and find the file (or just drag the picture in from the Gallery).
Step 2: Anchor the Picture As Character.
Right-click on the picture and choose Anchor > As Character.

Step 3: Position the Graphic Horizontally
Click NOT on the graphic but in the empty line NEXT to the graphic. Then just use the Left, Center, or Right alignment icon on the toolbar.
Troubleshooting: If the picture shows up about a quarter inch high, that's because the paragraph style applied has a height max on it. Nothing wrong with that, it's just not suitable for a style that's applied to the line a picture is on.
Either:
* Click in the paragraph marker next to the picture and choose Default from the dropdown style list
* Or click in the paragraph next to the picture, choose Format > Paragraph, Indents&Spacing tab, and select Single as shown.
Step 4: Position the Graphic Vertically
To control whether the
graphic is vertically at the top, middle, or bottom of the blank
line, right-click on it again and choose Align > Base At Top,
Middle, or Bottom. You don't have to do this if you think the way it looks is fine.

Optional 1: If you want to make sure that the graphic automatically stays with the previous line of text describing it, here's what to do. Select the text above the graphic, choose
Format > Paragraph, Text Flow tab, and select Keep With Next
Paragraph. Be sure to do this only with the paragraphs that precede
graphics or you’ll end up with unusual pagination.
You might decide
to create a specific style that you use for paragraphs that precede
graphics, and define that style with the Keep With Next Paragraph
attribute.
Optional 2: Click on the line, on the same line as the picture, and choose Format > Paragraph, Indents&Spacing tab. In the Spacing section in the middle, you can set spacing above and below the picture to space it so that it looks good and not too crowded up against the text.
Optional 3: Click on the picture and choose Insert > Caption to create a caption that stays with the picture.
The text, with a numbered field, will be inserted next to the picture, and the picture AND the new caption will be encased in a frame. That's how the caption stays with the picture.
Other Tips
A Setting You Probably Really, Really Don't Want
Here's what not to do. Right-click on the picture, choose the Type tab, and unmark the Follow Text Flow setting.
That will give you this result, with the picture going outside the margin. Yuck.
What About Anchor to Paragraph?
Anchor to paragraph is OK, as long as you don't unmark the Follow Text Flow option above. (I.e. keep that option marked.) You can drag the picture around with Anchor to Paragraph. But anytime you have that amount of freedom, it's possible to accidentally put the graphic where it shouldn't be. So I recommend trying Anchor as Character for solid graphics that stay where you put them.

Let's say you've got a big list of employees: name, address, etc. When you apply the filter and view, for instance, only people from Montana, some of the data isn’t shown. If you then copy, paste, delete, or perform other operations on the data, what happens to the data that isn’t shown? If you delete Artie Anderson from Montana and Cindy Chalmers from Montana, what happens to Betsy Bates from Nevada?
It all depends on the operation. Some, like delete, leave the unshown data alone. Some do affect the unshown data.
Operations that DO affect filtered out rows.
Cut and Paste
Move (dragging)
Fille (Edit > Fill or dragging)
Operations which do NOT affect filtered out rows:
Copy
Delete contents
Delete row
Format
Find & Replace in current selection

Cut and Paste, Versus Copy and Paste
With Cut and Paste, the non-shown data is cut and also pasted.
Click the following to see a bigger image.When you paste the data outside of the filter range, the whole set of data is pasted and unaffected anymore by the filter.
When you paste the data inside the filter range, the whole set of data is pasted, and all data is shown at first, even data that shouldn’t show for the current filter selections. However, if you re-apply the filter selections using the dropdown lists in the heading row, then the data is filtered correctly.
With Copy and Paste, the behavior is different. If you cut, you get the nonshown rows, but if you copy, you don’t.
Dragging Cells to Move Them
When you move rows (dragging) that include unshown rows, the behavior is the same as cut and paste. The unshown rows between shown rows are moved along with the shown rows.
Fill (Edit > Fill or Dragging the Cell Handle)
Here’s what happens with Fill. Here’s some sample data, and currently everyone is in the same department.
You now look at only people from Colorado.
You change the department for the first person from Colorado, and drag that department down through all the other people from Colorado.
Now, all the nonshown rows after the first row you changed are affected, but not the rows before that.
More About Operations that Don’t Affect Filtered-Out Rows
Copying and pasting, deleting, formatting, and Find and Replace don’t affect unshown data. The following section provides an example.
Deleting
Here’s a walkthrough of deleting rows while the filter is on. Rows that aren’t shown aren’t affected.
Look at the range from row 15, Dan Montbatten, to row 20, Beth Jerlin. Dan and Beth are both from Montana. In between are Jon, Marcus, and Kyle.
The next illustration shows an AutoFilter with only people from Montana, which includes Dan and Beth but excludes the three rows between.
Now delete Dan and Beth.
And they go away. However, when the state autofilter criterion is removed, Jon, Marcus, and Kyle are still there.
