I'm writing a function that I'd like to call whenever I plan to display an image instead of using the built in one, to give me a little more control over how images display. I found Pixie's very excellent tutorial on the subject and see lots of neat options.
Is there any way to set a pair of variables to equal the height and width of an image using a variable that contains the filename of the image? So that I can (for instance) decide on whether I want text to wrap around an image based on whether its width leaves enough space or not.
Oh well. I guess time spent learning things is never wasted.
