Yes. For any block type bt, if it makes sense, it would be possible to write such org-block-<bt>-generate-image(body) that takes the block as argument and returns the path of the image it produced. Then: - for exporting: the existing org-export-blocks-format-<bt> functions would simply call their respective org-block-<bt>-generate-image and work the same ; - for previewing a block of type <bt>: if such org-block-<bt>-generate-image exists, call it and display it the same way org-format-latex does Wouldn't it be great ?
