Imagecache appears to give Images a long past expires header: 11/19/1978.
Because of this Browsers cannot cache the images, which impacts performance massively. In Gallery-like Views like this;
http://netzschwimmer.de/temp/audioclassica-test/de/audio-klassiker/angeb... page loads takes quite some time. If I have even more images on one page, like here: http://netzschwimmer.de/temp/audioclassica-test/de/music-link-cd-23 I had to find another solution that circumvents Imagecache. The page was loading extremely slow.
What makes it worse that the long load time is repeated every time a user reloads the page. Only firefox seemingly caches the image, until page load is completed, it takes also Firefox quite long. Using Yslow one sees the many Http Requests that are slowing down the page load.
Is this a bug or done by will? As one can wonderfully use views for Image Galleries and the kind of Navigation with Images I use, this stops Imagecache from being usable for that, which is a pity.
Maybe there is a way I can tweak this, even If you want to keep it for the normal release?
