Putting the image sizing support +into a plugin instead of trying to shoehorn it into a wikilink seems like +the way to go. + +I have two issues with this plugin as it's implemented now, the first is +that the generation of whole pages containing a scaled version of the image +seems gratuituous, as well as buggy. If you want three pages with +differently scaled versions of the image, why not just create three pages +and use the plugin once per page? Something like this on the first one if +it's got multiple clickable thumbnails: + + \[[img foo.jpg width=256 link=page2]] + +This on the second: + + \[[img foo.jpg width=1024 link=page3]] + \[[small|page1]] + \[[medium|page2]] + \[[large|page3]] + +This on the third: + + \[[img foo.jpg link=page3]] + \[[small|page1]] + \[[medium|page2]] + \[[large|parge3]] + +Granted, this is more work, but it's more flexible too, and it doesn't have +it creating new pages on the fly, which I don't personally like.. + +---- + +The second issue is whether it should use imagemagick to scale the image +and generate a new scaled one, or just emit html that sets the sizes of the +image. Benefits to scaling: + +1. Saves download time and bandwidth, especially if generating a page with a + lot of thumbnails of large images. + +Benefits of not scaling: + +1. Avoids any security issues with imagemagick. +2. Avoids issue of how to clean up old scaled images that are no longer being + used. (Granted, this is a general ikiwiki problem that will eventually + be fixed in a general way.) +3. Makes clicking on thumbnails display the full version really fast, since + it's cached. :-) + + +--[[Joey]] -- cgit v1.2.3
