How to change inline picture baseline?

Question

I often include small inline pictures in my chemistry texts. They are for example safety pictograms that I add when I mention some dangerous compound. While small, these pictures are often a bit larger than the text line height.
The problem is that the bottom of the picture is aligned with the text baseline. This is a problem of balance: the top of the picture is then far too high compared to the text.
What I would like to achieve is to vertically center the picture with respect to the text line. This means lowering it quite a bit.
I had hoped to use Format>Font>Baseline>lower, but that command is disabled (unsurprisingly as a picture is not text).
Is there a solution? Switching the picture to be floating instead of inline is not a solution, as it then in practice prevents the text from being edited, lest the picture be moved away from its proper location in the text.
Thanks for any help.
I'm not sure my description of the problem is clear enough. If warranted, I can improve it with screen shots.

Fruhulda,
Thanks: you are right, using the text inspector More pane works: you can select the image only and shift it from there.
So now the issue is only an issue of consistency: the same command is enabled, and works, in the inspector, but is disabled in the menu.
Peter,
I'm not sure I understand your question. Which "two methods" do you have in mind? Let me describe my expectations:
- I expect to be able to shift text vertically on the line. It turns out I am right. To do so, the user selects the text to shift and applies one of the command in the Format>Font>Baseline menu (eg Raise, Lower). Alternatively, as Fruhulda reminded me, the user can use the More pane of the text inspector. All this is documented in Pages '09 user manual on page 82.
- I expect to be able to shift an inline image vertically on the line too. It turns out I am also right. To be consistent, the user would select the "thing" s/he wants to shift, ie the image, then would choose Raise/Lower, in exactly the same way as with text. Alternatively s/he could use the More pane of the text inspector.
Yet it turns out that, out of those FOUR scenarios, only THREE work:
1- shift selected text using the More pane of the text inspector: WORKS
2- shift selected text using the Format>Font>Baseline menu: WORKS
3- shift selected IMAGE using the More pane of the text inspector: WORKS
4- shift selected IMAGE using the Format>Font>Baseline menu: DOESN'T WORK
That scenario 4 doesn't work is not consistent. It should work. As a user-interface designer, I consider this misleading behavior a bug.
Note that you can select the image in three ways: by dragging over it, by clicking on it, or by putting the caret just before (resp after) it, then typing shift-right arrow (resp shift left arrow). As far as I could tell, it doesn't make any difference how you select the image.
All in all, after going to the very bottom of this barrel, I am grateful to both of you: I can now shift my images in a satisfactory way (using the inspector). Many thanks.
