I've visited a few new food blogs recently (finally having time to read again!) and have noticed that many bloggers seem to have a misconception about how images work on the web. If you have a large image and you set the size to be something different than your original in the html code, your readers are still waiting for the huge image to download and their browser merely rescales it to fit in the size you've decreed. If you want to create a reasonably sized image for download, resize it in a graphic program before uploading it somewhere and linking to it from your blog. For me, something under 100k is reasonable although I usually shoot for less than 50k but if you're taking full size images from your digital camera and not resizing them, you're forcing your readers to wait for a huge file to download very slowly. And they also, by the way, blows up to the whole screen on RSS readers. The one I just ran into, the third blog with huge pictures in the half a dozen blogs I've read this evening, was a 1.2 Meg file, although it was set to display only in a roughly 200 x 200 pixel space.
