If your images are truly tiny, you can create them as a glyph in a font. I do this frequently for fleurons and dividers, and then use a font size of 3em up to 8em to make them display large enough for the purpose.

I use Inkscape to do a bitmap tracing of the image, and then import that resulting svg into my font editor and create a custom font. (Type3 from CR8 software --- free demo is pretty much feature-unlimited, time-unlimited, but will only save a max of 50 characters) If you find this interesting, maybe I could put up a small tutorial.

EDIT TO ADD: I have successfully used images up to 600x600 px to do this, the font editor lets you scale the svg to a usable size. You could probably go even larger, but I have never tried.

The great thing about using this method, is that the decorations are part of the font, and will change color along with other text if the user chooses to use night mode, sepia, etc.
