Didn't cover the pictures in the right place, eh? That's easy to fix as in each pet page is different. Anywho, you have to open your CSS file. If it's on freewebz, then you can edit it right on the account. geocities won't let you do that, so you gotta keep re-uploading the changes. Check to see if your host will let you edit it.

Find the picture that's off place that you want to move. What letter is it? Find the same letter (a,b,c, or d) on the CSS file and that's the part of the code you'll alter.

You'll notice that each image position has the same layout:

Alrighty. To move a picture up, you make the "top" number less. As in a smaller number. To move it down, you make that number greater.
To move a picture to the left, you make the "left" number smaller. To move it right, you make the number less.

it's very simple. Now save - upload if you must, and refresh the pet page. Make sure you have no new events at the top of your screen. Keep fiddling with the numbers till the correct pictures are over the correct images on the page.

You're Done!
