Has anyone else noticed my comics seem to be aligning themselves more and more to the left? I can't figure out why it's doing that, they're supposed to be centered. It's real weird. Please speak up if you have any input on this.
Maybe
since the background is white on your template, just add white on the left side of your comics. And then when you upload them they'll be pushed to the right?
The issue is that your comic is in a table that is centered on the page. The table is set to have a 500px width. If the comic is near or over 500px wide, it looks fine because it takes up the whole table. But, when the comic is much less than 500px wide, the contents (i.e. your comic) are aligning to the left side of the table, which is the default.
To counter this behavior, the easiest thing to do would be to change the <td> tag that contains your comic to the following:
<td align="center" >
Doing this should center all your comics. Let me know if you have any issues.
