Re: [julia-users] Escher image update

[Shashi Gowda]

This is browser caching at work

one way to resolve this is to just imread the image instead of loading it
using image() which just creates the equivalent of an  HTML tag...

e.g.

using Images

run(`convert a.jpg  assets/a.jpg`)
imread("assets/a.jpg")

Sorry the problem is actually not even browser caching... what happens is
Escher thinks there is nothing to update because the URL attribute remains
the same...

imread is a good solution although slower. Another good solution is the one
you yourself gave if you can figure out a way to clean up all the temporary
files it creates.

Thanks, yea I just asynchronously clean everything *.jpg in assets/ before

You can put the image in the assets/ directory under the directory you
started the server in and then show it with image("assets/img.jpg")
