Need configurate icon_sizes.

[zcho]

For many designs the standard size does not fit.

In actions/avatar/crop.php and actions/avatar/upolad.php

@todo make this configurable?
$icon_sizes = array(
...

Yes. Plz make it configurable, may be in admin section, or engine config.

Agreed. We need to balance adding options against performance (more db calls potentially) and complexity. It does seem like this one passes the test.

We should add the ability to update previously uploaded avatars to the new sizes.

In general, I think the solution should be that the system is passed a pixel value for the size. If a version of the icon with that size doesn't exist, one is created and cached on the fly from the master copy. We can also come up with a way to support different icons for diminishing sizes as is the case with page icons for example.

Developers would still be encouraged to use the "size" keywords (small, medium, large, etc) so as to be cross-theme compatible.

If the system optimizes this by caching the pixel values of the keyword sizes upon upload, that's fine too, but also generating new versions on the fly from pixel sizes means 1) no need to run huge upgrade scripts that converts all existing images -- they'll get "converted" over time as people request them, and 2) independent services could integrate the avatars/icons from an Elgg installation in precisely the right sizes appropriate for *their* theme, similar to how the gravatar plugin works with gravatar.

Is this done?

Yes. Icon sizes can now be configured through settings.php and there is another ticket for dynamically generating the images.
