After discussion with some people (especially Tannin)
on the
en.wikipedia, I propose a few changes (more like additions) to the
thumbnail function.
Here's the "main proposal":
[[image:bla.jpg|thumb|some text]] generates a normal thumbnail
[[image:bla.jpg|thumb=bla_small.jpg|some text]] uses "bla_small.jpg"
as the thumbnail
This would be very useful due to the fact that cropping needs to be extreme
with images that are displayed as small thumbs while cropping can be more lax
for images displayed as larger thumbs, and very lax on image description pages.
Alternatively one should be able to redirect the image page of the thumb to
point in the right place, but the result of that is ugly (the image from the
redirected page and the target page are displayed on the same page). Another
idea would be to specify the crop from within the image code, thus eliminating
the need for two uploaded images:
[[image:blah.jpg|thumb|crop=right10%;left15%;top5%;bottom20%|some text]]
Other things that would be *very* nice
*re-enable the center tag
*create a 'caption' tag so that captions can be easily added to images which
are displayed at their actual size in articles. The only difference in look
from 'thumb' tagged images, would be the absence of the box within a box icon.
...
Additionally, the automatic thumbnail generation should be improved:
* Add a little sharpening, at least to photos (.jpg/.jpeg).
* Apparently, automatically generated thumbnails look nicer when they
are recaled by an exact even number. For example, for a 640x480 image, a
thumbnail of 200px is requested, generate one with a width of 213px
instead, as this is a factor of 33.3%, or 1/3. I propose to use a
variation of up to 10% from the requested width.
This might be ugly on pages were images are in a series box or otherwise close
to one antother (thus size differences would be obvious). See
