I'm new to WordPress, so please forgive me if this is an easy one, but I've searched around a bit and can't find an answer to this question:
When I set up a simple gallery page, the thumbnail previews are actually the full-size images, just resized with simple HTML tags (e.g. <IMG WIDTH="120" HEIGHT="150" SRC="...). This is sort-of OK, but not really optimal. Is there a setting (or plugin, perhaps) that does a server-side resize, or generates proper thumbnails at the time of upload so that the viewer doesn't have to download all the full-size images in order to see the thumbnails?
Thanks very much for any help or suggestions.
