When you do org-preview-latex-fragment, a ltxpng subdirectory is created under the directory that contains the org file. So if you have /home/joseph/foo.org and you preview it, you are going to get /home/joseph/ltxpng as a subdirectory. That is controlled by the setting of org-latex-preview-ltxpng-directory however: ,---- | org-latex-preview-ltxpng-directory is a variable defined in `org.el'. | Its value is "ltxpng/" | | Documentation: | Path to store latex preview images. | A relative path here creates many directories relative to the | processed org files paths. An absolute path puts all preview | images at the same place. `---- So you could customize it to store all the png files into /tmp/ltxpng e.g. No idea where the tmp/ directory comes from, but I don't think it's from the preview.
