Hello! I'd like to cache images (order of hundreds) from a remote location (not all the time mapped as drive, download speed and amount of data are also the factors). \usepath[dirfile://./resources/**] is likely for speeding up searching not downloading and I don't know when new images are available (when to delete dirlist.* files), as described in workflows-mkiv.pdf. Looks like the cache parameter in \externalfigure is used only if some conversion is going on. I could create a conversion which does nothing or only envelopes JPG in PDF as <id>.jpg.pdf (loading could be faster) and then: if cached file exists use cached <id>.jpg.pdf else if drive is mapped download, convert and cache <id>.jpg else skip file end end The source file with one <id> will never change or I could re-cache from time to time to have up-to-date images cached. Before reinventing the wheel: isn't such functionality or part of it already available? Thanks, Jano
