support on-demand image sizing
Ticket
+issues
the default image sizes don't suffice in some cases. although there are currently workarounds that involve browser resizing (described in example section), multiple wagneers have requested support for automatic server-side resizing.
+solution
inclusion syntax already accepts a "size" argument. In addition to the current named sizes (icon, small, medium, etc), we should also support explicit sizes using some variant of Image Magick resize args.
So to resize an image to 100px by 100px, you might do
{{myimage|size:100x100}}
+example
currently, if you want to use browser resizing, you have to add something like this to your CSS:
.TYPE-image .content img { max-width: 100% }
and then do this in your inclusion syntax:
{{myimage | size:large; width:300px}}
The preferred solution is described in the solution section.
