Using the Gallery: removing the descriptive text

In years of using OO/LO (now @ 7.1.4.2), I have never been interested in the Gallery of multimedia objects. Now I have an application for it, and can't see how to execute a simple inclusion of a graphic without its attached descriptive text.

Specifically: in Writer I have a 4-page booklet/pamphlet in which the two facing inner pages have related content: The left side (page 2) has a list of summarized thoughts (each a few lines), two of which are expanded on the right side (page 3). To help the reader make the connection, it seems helpful in both cases to point from the condensed version to its expansion. The Gallery has a set of "Flow chart" graphics, including braces and brackets designed to serve the function of grouping a few lines and pointing to a conclusion. Unfortunately, all come with the description "Callout" which is inserted along with the graphic -- kind of like clip-art that includes a message "This is clip-art" (as part of the clip-art display). This can't be right, can it? - yet I have searched in vain (including the Help and Guides) for how to turn off that descriptive text. What am I missing?

IMHO, the flowchart symbols are not suitable for your purposes.
For graphical symbols that should contain text, text boxes, drawing symbols or frames are suitable.
Please have a look if this article helps you:

Thanks, Harald. That article is about using frames (including linked frames) to layout a DTP project; it does not address the Gallery, or even the inclusion of graphics generally. FWIW, I'm familiar with frames (and even use them in this document), but don't see how they relate to the question of included graphics, from the Gallery or elsewhere.

Most of the Gallery contents seem to be traditional clip-art (graphical symbols), including those collected in the "Flow chart" category. How do those flowchart symbols differ from others? [The Gallery has three other categories - "BPMN", "Diagrams", "Shapes" - that also contain descriptive text with graphics; my original question would also apply in those cases.] Is your point that I should forget the Gallery and make my own graphics (from Draw or elsewhere)? (If so, what is the purpose of the Gallery?)

Kind regards,
John
